Haskell vs ocaml. Laziness or, more strictly, non-strictness is big.
Haskell vs ocaml And ocaml also seems a much simpler language than just going full crazy on haskell and is much more pragmatic. Add Comment * Both Haskell and OCaml are highly suitable for langdev. [Haskell-cafe] Haskell vs OCaml Hal Daume III hdaume at ISI. 1s, which is what I would have expected. One could represent represent coordinates on plane with a simple pair tuple with this type: May 3, 2023 · There is a nice library for GC in Rust, so this is not a clear advantage of OCaml or Haskell anymore: GitHub - kyren/gc-arena: Experimental system for rust garbage collection. I liked Clojure for the pragmatism and made my way to OCaml later for the same reasons. OCaml vs Haskell: A Comparison of Functional Programming Languages. xyz/) should have everything you need. Previous message: [Haskell-cafe] Haskell vs OCaml I have never used Scala, but I have used Ocaml, another mainly functional language. But working with linux and systems stuff feels nicer in ocaml imo. Nov 19, 2022 · So, in my opinion, the general learning resources for OCaml are already of high quality and we don’t necessarily need more (though more would be fine, too), but what should change is the culture around documentation, so the average OCaml library author will feel inclined to explain how to use their libraries to other programmers. You will notice that a big difference in the Haskell and OCaml ways of doing it, is that in Haskell, when you use that last function, the compiler infers the proper instance of the type class for you; whereas with the OCaml way of doing it, the user must explicitly specify the instance to use. Ocaml's Owl library (https://ocaml. Haskell is a very popular language in the functional space, it is packed with features, has an active and prolific community with an endless series of blogs and cool libraries. Aug 11, 2021 · I’ve written a blog titled “General thoughts on Ocaml & Haskell and OCaml’s (supposedly) pathetic state of tooling” I wrote this in partly in response to some of the views expressed in Expanding ocaml appeal to future open source application developers" and similar discussions that have taken place in the past. Your email address will not be published. F# and Haskell are both functional programming languages that share many similarities, but they also have notable differences. EDU Fri Dec 23 19:46:48 EST 2005. The common case of a simple variable name (like acc in your first function) is just a particular kind of pattern that matches all values. install . Both Haskell and Clojure have better stories here, IMHO. I’m interested in functional programming, so I think this will be one of Haskell or OCaml. So I thought maybe some of them are overlooked and decided to post it here: pidigits source seconds memory gz busy cpu load F# 1. 96 19,464 458 11.

Here are six key differences between F# and Haskell: Type Inference: F# has a more flexible and lenient type inference system compared to Sep 21, 2009 · Note that the former limitation does not exist in OCaml because subtyping is structural instead of nominal, so the structural type is easily refined via unification as type inference progresses. You wrote interface twice when you meant something else (implementation?) the second time. Sep 27, 2024 · Functional programming has gained traction in recent years, with languages like OCaml and Haskell leading the charge. This shouldn't be a big deal, but as Mar 16, 2023 · OCaml gives me more power while feeling leaner to work with I envy some strides F# made, but I don’t like the idea of replicating them. tail . I wish Haskell was as beginer friendly as Elm, I wish OCaml had better Windows support, I wish F# was more functional without huge OOP baggage, I wish Elixir was statically typed, I wish Elm wasn't only a JS-compiled language. They went instead with a Haskell-like typeclass system with methods, which effectively leads you to OO-like design/programming. Except that in OCaml you can use = on every kind of value, whereas in Java you can't use equals on primitive types. I actually came up with a complete Haskell implementation of my example here . Sad. May 3, 2013 · So what about OCaml? In OCaml, a functor is not a type—it's a module. 80 183,360 1907 19. Ironically, the only compelling pragmatic application of higher-order modules I have ever seen is Cohttp's use of functors to avoid code duplication when supporting both Async and Lwt. It unlocks exciting possibilities for application-specific introspection. For a compiler and especially the type checker written with Haskell I just remember that talk of an experience report held at SLE conference (co-located with SPLASH) in Athens, 2019. There remains the OCaml appears be somewhere in the middle [between Haskell and Go]. OCaml is simpler and more pragmatic than Haskell (and also: much less emphasis on purity, and less expressivity for type-level computations). Did I miss anything? OCaml is a functional programming language in the ML family, an extension of the Caml language with object-oriented constructs. When it comes to functional programming, two popular languages that come to mind are OCaml and Haskell. Both Haskell and SML have pattern matching which makes describing a recursive algorithm a cinch. Note 3, because I'm biased in favor of OCaml: OCaml does produce far more performant systems than Haskell, generally. [Haskell-cafe] Haskell vs OCaml Albert Lai trebla at vex. > What are the advantages of lazy evaluation? The advantage of lazy evaluation is that evaluation order becomes one less thing you have to think about. – Feb 14, 2023 · > I think Rust's features were actually inspired by OCaml rather than Haskell. These three languages seem to bring a lot of the benefits Elm brings to the front end. Both OCaml and Scala are powerful languages that have distinct features and advantages for different use cases. Having this said, I don't see me doing anything much serious ever in ocaml. Haskell has a simple emacs mode, and you can probably use OCaml's tuareg-mode to edit F#. That leaves one aspect of Haskell vs Ocaml I don't yet understand. Your example may be written on Scala or C#. > OCaml feels a lot more similar to Rust than Haskell does. Let’s compare them: Next-fit, the original and remaining champion. NET port of OCaml and to some extent it is not ideoligally clear as Haskell is or as OCaml is. Apr 26, 2023 · Simply because OCaml and Haskell languages are similar in many ways. There are 7 free Haskell compilers and interpreters, there is 1 OCaml implementation. com Oct 28, 2023 · We will overview how Haskell emphasizes purity and laziness, while OCaml allows side effects and eager evaluation. As much as I think Elixir / Erlang are amazing tools, and probably the best for dealing with "fault tolerance" issues, I wonder why the Elm community is not leaning towards using other established ML-style languages like F#, Ocaml or Haskell. F# vs Haskell: What are the differences? Key Differences between F# and Haskell. A couple of dozen different programming languages. ) But you can’t just have an excellent type/safety system at Nov 7, 2019 · Hello fairy camls, While learning Ocaml I stumble upon many ideas (e. Ocaml was my favorite language from 2004 to 2008 when I transitioned to Haskell. Given the former, what the programmer team has to do is kind of take a cold shower and write them “artifacts” without going hog wild with all those cool features that are just begging to be used. Previous message: [Haskell-cafe] Haskell vs OCaml Next message: [Haskell-cafe] Haskell vs OCaml Messages sorted by: > However, the biggest advantage that ocaml has over haskell is that for most > applications, an ocaml program will run faster, perhaps a lot faster, than > an equivalent haskell program This for me is a big win because most of my code requires a lot of pure number crunching. Dec 6, 2011 · Haskell did away with the archaic let vs. Both OCaml and F# guarantee that all calls in tail position are eliminated (under appropriate circumstances). Papers are referenced and many are written in Haskell rather than SML or Ocaml. Map used to be part of the standard library. Already, we can see some parallels: in Haskell, a Functor is like a type-level function; in OCaml, a functor is like a module-level function. Ocaml is pretty easy when compared to haskell tho, especially because it's easy to use an impure approach and even OOP if you feel like it. With that disclaimer in mind, the second option looks quite nice, to my biased eyes. Required fields are marked * Name * Email * Website. Java has “strong” static typing. OCaml 5. I'm leaning towards Haskell for the reasons outlined below, but I'd like the opinion of those who are active programmers in one or the other. Aug 24, 2018 · update 17/09/2018 - added multiprocess OCaml and Go+goroutines results update 28/10/2018 - added async OCaml results The Go version straight out of the box demonstrated the best performance. OCaml Haskell vs OCaml: What are the differences? Type System: Haskell is statically typed, while OCaml is both statically and strongly typed. May 20, 2024 · This article will delve into several critical aspects of the OCaml vs Haskell debate, including their type systems and type inference capabilities, the impact of functional purity and immutability on coding practices, and how each language’s performance and evaluation strategies can influence application development. You may also have a look at the following articles to learn more – WebGL vs OpenGL; DirectX vs Vulkan; AutoCAD vs SolidWorks; AutoCAD vs FreeCAD Mar 6, 2023 · Haskell Vs OCaml. After looking at Scheme, Erlang, Haskell, Ocaml, and SML, I've settled on either Haskell or Standard ML. I'm not an expert - F# AFAIK misses some of the higher level type theoretic stuff, but you can write 'basic' Ocaml that would be isomorphic with F#. To date the containers package (which contains Map) is still pre-installed alongside the GHC compiler. F# started from Caml core syntax and has many similarities. My feel is that OCaml is on an upward trend. It allowed me to get things done with a mixture of functional and imperative programming. net has aspnet and all the c# libs. Its compiler is faster, and the performance of programs (time and memory) is more predictable. Net and then added all sorts of pragmatic language constructs. But what about all the other cases? So, more concretely, there is a library A that provides some type A and a library B that provides a trait Previous message: [Haskell-cafe] Re: Haskell vs OCaml Next message: [Haskell-cafe] Re: Haskell vs OCaml Messages sorted by: G'day all. You need to abandon every other feature that you consider nice to have, just to rescue this one. Mar 23, 2020 · OCaml used to propose 2 free-list allocation strategies: next-fit, the default, and first-fit.

Just to be clarify for other readers of this thread: in order to achieve the kind of usability that is found in Haskell and Rust, you need both mechanisms, type classes/modular implicits and “deriving”, simultaneously (and indeed both Haskell and Rust implement both mechanisms). In Haskell, I used to dread moving functions to the toplevel scope because they’d need annotation. Such a large difference to me indicates that one programmer has a much better intuition of performance which (subconsciously) guides him. – Should I learn Haskell or OCaml?Haskell is the dominant language of functional programming research, running everything from climate models to data crunching Dec 31, 2011 · Still, you have to understand Haskell (or OCaml) type inference. Spent ~10 years at a Haskell shop, and currently at an Ocaml one, and was a Standard ML hacker prior to the Haskell job. Mar 28, 2020 · Running this benchmark on my computer for both Haskell and OCaml, I get considerably better numbers: OCaml needed about 2. OCaml was born in 1985, Haskell in 1990. Haskell is definitely a great language and, I think, a mandatory point for the aspiring gurus of functional programming. – May 3, 2005 · Marcin gives a good capsule description of the differences between ocaml and haskell. I should also mention F# as an alternative. It is in the process of addressing, or has already addressed, some major pain points: multicore and better control of impurity (via effects). Pro-Haskell: Haskell does datatype constructors right. And yes, I mean just non-strict semantics, divorced from purity or anything else. F# started as Ocaml for . OCaml's simplicity helps when working with the compiler. At the end of the day it matters what one gets done with one's own problem and data. ml file: type 'a my_type = 'a -> unit let foo (_ : 'a) = () let bar = Fun. Is this roughly accurate? It's nothing fundamentally new that you couldn't do in Haskell or OCaml or Common Lisp before, but it is a very attractive package, easy to transition to and be productive quickly without having to relearn how to program. If anyone can weigh in with some thoughts, it’d be appreciated. That said, I’m much more familiar with Haskell than with OCaml, so if you think there is a mistake in the text, let me know.

On Tue, 3 May 2005 21:04: Dec 28, 2021 · modular implicits will do all this for OCaml without having to give up on the beauty of modules and functors. For them, a post like Edward’s that mosty focuses on the “limitations” of OCaml compared to Haskell, and provides succinct high-level descriptions of OCaml’s unique fea-tures, is sufficient. What’s the difference between OCaml and Reason, ReScript, Buckescript, and so on? If I'm limited to the list in this post, that eliminates Haskell, Scala, OCaml (and probably Rust) immediately. Sep 16, 2023 · compilation speed and tooling (rider/vs) are much better than scala’s the language isn’t as flexible/featureful, but has many good practical features (e. ml", line The two languages are close enough that "I don't like OCaml because it's not like Haskell in X ways" is actually useful. IMO, OCaml is more simple and nicer for certain algorithms and patterns that are common in langdev, for example fresh id generation and destructive unification is more natural in an impure language and these are important concepts for a compiler. Apr 26, 2023 · The Golang/Haskell runtimes have been doing things for years for which OCaml 5 has just acquired capabilities. Feb 18, 2020 · The question Idris vs. When I used OCaml, I never touched the OO bits, but they certainly exist; Haskell has nothing in that area at all. But the thing that always amazed me about OCaml was how such a small community could remain so fragmented like Core Async vs Lwt and Cohttp vs HttpAF. A decent compiler can see very well if it's a simple let or one that contains mutually recursive definitions and can act accordingly. Haskell takes a different trade-off, choosing to focus on predominantly-pure code where these limitations can be lifted. But according to the The Computer Language Benchmarks Game Haskell oftenly beats OCaml, if only by rather small fractions. This difference can affect how developers write and interact with the codebase. mli file: type 'a my_type = 'a -> unit val foo : 'a my_type val bar : 'a my_type λ> dune b File "lib/ocaml_bug. It’s absolutely necessary to make the type system work in Haskell and Rust, but I dislike it. Not really. Oct 26, 2016 · It is more practical than LISP I think (because it's type system) and more powerful and clever than F#. But for the last 8 months, I used OCaml at Bloomberg. Since OCaml and Haskell have both tuples and tuple product types, it is worthwhile to consider the differences. The Haskell version, after some tinkering, came second, and the OCaml version, while being slower than the other two, was champion in memory consumption. head << List. Not that this guideline was followed for all the examples, but the paper seems less about a rigorous comparison than to compare various language environments for their "whipitupitude" factor -- an important metric where I believe haskell still lags behind (but is making gains) but where I found Ocaml did even worse (but I last touched ocaml >10 No, on the whole I think (single-threaded) Ocaml binaries tend to be faster. Mar 14, 2023 · Ocaml: Setup opam, dune, lsp. As far as C++ goes, I like to think that Scala is the C++ of the functional world; it certainly seems to have far more features than Haskell. OCaml syntax is OK but suffers by comparison. Haskell tends to have a lot of ways to solve one problem: formatter vs no formatter, what kind of tests to write, plain IO or effect systems, etc. computations, purely functional datastructures, GADT) and teachers here know what more next, not to mention hordes of use cases (difference lists seen here a month ago ( adapted from haskell)).

Here we discuss Haskell vs OCaml key differences with infographics and comparison table respectively. A controversial start, perhaps, but I stand by it. (That said: once you get one FP language, you'll be able to carry the fundamental principles to other languages pretty easily, and they might be useful in the future. Laziness or, more strictly, non-strictness is big. . tail But Haskell and OCaml are rather different languages, and even if you try to stay as close as possible, there are still choices to make. January 15, 2022. Let me add my two cents. net cli. Agda. Overall I felt the blog post was a bit too critical about OCaml. Leave a Reply Cancel Reply. Wadler has many references (at times in Ocaml) to May 3, 2009 · Here I compare Haskell, Clean, OCaml, Lisp SBCL, C# Mono and Fortran because they are all in the same ball mark: 32-bit sing core [1]: Lisp, Fortran, Clean, Haskell 从特性角度讲，Haskell和Ocaml在核心类型系统上非常相似，都是HM+一些fancy feature。实际的语义上Haskell是惰性语言，而Ocaml是常规的by value语义。惰性求值迫使Haskell使用monad管理副作用，而ocaml则比较自由。 语言差距最大的在于这两者是如何处理模块化问题的。 Except for (2), Haskell seems to have met all these goals. Ocaml was a great preparation for Haskell. OCaml has an inherent speed advantage from its tight type system and compiling model. In contrast, an OCaml programmer is often someone who has learned OCaml Being rather new to OCaml it is difficult for me to be objective about this, as I'm still getting used to the syntax and somewhat attached to how things look in Haskell. Background and users OCaml is weaker even when just looking at parallelism, given its underlying architecture. Another difference is that floating point numbers in OCaml are reference types, so you shouldn't compare them using == (not that it's generally a good idea to compare floating point numbers directly for equality "the OCaml compiler is more aggressive at tail-call optimization than F#". OCaml is supposed to be very fast, and Haskell perhaps is not. As for ML vs Haskell/Erlang, it depends which ML.

[Haskell-cafe] Haskell vs OCaml Joel Reymont joelr1 at gmail. One consequence of that is that effect handling is the most popular conversation topic between Haskell devs and most Haskell programs require reading five academic papers before you understand what’s going on, and the simplest system relies heavily on ad-hoc polymorphism and advanced type-system features making it really hard to Dec 28, 2023 · Hi everyone 👋 I’ve been using Haskell in production for the previous 8 years. The reason I switched from Ocaml to Haskell was that I saw Haskell's strict control over side effects as a distinct advantage. Both are functional and have fairly clear syntax. OCaml is strict by default, although it has some facility for introducing laziness. Haskell. Jan 8, 2024 · I received tons of feedback on my OCaml vs Haskell blog post! Thanks a lot to all who read and shared their thoughts 🤗 Using the feedback, I improved my post by: Changing the most triggering exponentiation example to a different one Added links to all discussions of my blog post all around the Internet Changed feature from Laziness by default to Composable laziness Added topiary as an OCaml OCaml vs Haskell. On the one hand insanely fast compiler (much faster than Go’s!) and a sophisticated type system (and more powerful module system than the other two) make it extremely pleasant to work with. Dec 1, 2020 · I found this strategy quite useful in Clojure, where the default sequences are lazy. Even the way OCaml code is organized, into interface and implementation files, is (superficially) similar to how C is organized into header and source files. (4) is a very significant feature of the Haskell community which is luckily coherent enough for this not to stop new ideas. Since then, I've gone back an forth between "OCaml is the future" and "But Haskell is so pretty. Apr 29, 2019 · Comparing the Same Project in Rust, Haskell, C++, Python, Scala and OCaml.

One, INRIA is full of people who are way better at compiler optimization than any human has a right to be. Haskell vs. Haskell uses type inference to deduce types, which can lead to more concise code, while OCaml requires explicit type annotations. Sep 7, 2023 · The Deref trait only helps you in one specific case (going from the new type to the old type, which is just syntactic sugar for &x. […] Haskell doesn’t include Map and HashMap; The Haskell standard library was split off into smaller parts. Haskell also has an older Visual Studio plugin, but I don't think it ever got out of beta. Two such languages, OCaml and Haskell, are both functional programming languages but approach modularity and type abstraction in distinct ways. For the last 8 months, I’ve been using OCaml at Bloomberg, and my focus switched to a different language from the ML family. type providers) it’s OCaml-ish and much of your OCaml knowledge translates 1:1, scala on the other hand would take a bit more time to get up to speed with.

Take a look at this section to gain an understanding of Haskell and OCaml programming languages. OCaml is a variant of the ML programming language family, while Haskell is a purely functional programming language. Specifically, you need a dynamically typed Ocaml vs Python: faster; Ocaml vs Ruby MRI: faster; Ocaml vs C++: slower but less code; Now, we all heard the line about lies, damned lies and benchmarks so grains of salt recommended -- but this a fairly well done comparison. I wrote a blog post comparing two languages from my POV: Dev. They both offer powerful features, such as parametric polymorphism, algebraic data types, and type inference, but they also differ in their purity, evaluation, type system, syntax, concurrency, and ecosystem. The Haskell compiler (well, GHC, which is the de facto Haskell compiler) works a lot harder than Ocaml's to optimize because, vaguely speaking, Haskell's computational model doesn't resemble your computer's computational model as much as Ocaml's does. Plus, ML in general is gaining exposure with Rust, Swift and Scala. I completted a course, and wrote a Revers Polish Notation calculator. Besides that, what else could you say about them? > Both Haskell and OCaml have kinda barebones standard libraries. Reply reply Ocaml is a bit easier to reason about w. OCaml doesn't even have type classes/traits! Jan 9, 2021 · OCaml doesn’t have typeclasses like Haskell/Rust or implicits like Scala, but it has an incredibly powerful module system that is as expressible. Another unique feature of Haskell is that it is also a "lazy" language. F#: get rider. So, aside from fuzzier philosophical differences, what stands out in Haskell vs OCaml? Laziness. As far as you know F# is a . Meanwhile, OCaml has a ton of stuff that they really should prune and have not.

Using the feedback, I improved my post by: Changing the most triggering exponentiation example to a different one; Added links to all discussions of my blog post all around the Internet OCaml and Haskell support both types of product type. It is that minor of a concept, and incredibly close to extinction. r. SML also promotes constructors to functions, and Caml Light used to. But even OCaml follows a similar path--the O in the name is not a joke, after all. I also learned ocaml before learning haskell, and the biggest single difference I found is that haskell is a lazy, purely functional language and ocaml is a strict, "mostly functional" language. Additionally, OCaml's garbage collector is optimized for performance, which helps in managing memory efficiently. 10 of OCaml introduces the new best-fit strategy. Write your typical applications from your domain. JaneStreet is a big OCAML supporter but I am really not sure about developer support and help forums for OCAML. This is in my opinion the most difficult of the three, if you care about proofs (otherwise, choose Agda if you don’t need to compile to Ocaml or something special like that). I used the strategy in a project in OCaml too, first with Batteries. If you want to learn loads of new things with more purity and type shenanigans then Haskell would be a pretty good pick. Side effects : Both languages make it pretty obvious when you are mutating variables. I don’t have particularly clear-cut requirements here, but here are some things I have been working on, as well as other thoughts I have been having about this choice, that may May 2, 2023 · On the topic of type annotations, I’m pretty happy with where OCaml is. gasche: has recently benefitted from lexi-lambda’s impressive delimited-control primops work that certainly opens the door for runtime-supported algebraic effects for Haskell. Sep 20, 2024 · Programming languages often come with their own unique features that cater to different paradigms and styles. Please point out that compliler really has enough information to infer the type, but the type can not be inferred due to language specification or due to local-only nature of type inference in Scala or C#. Haskell Performance. I'll recommend you study Haskell or OCaml to know how inconvinient F# is. There are deep reasons why constructors are slightly particular. NET seems especially attractive. However, OCaml is probably using much smaller stack frames than . net’s because . Haskell, while also capable of producing efficient code, often prioritizes expressiveness over raw speed. to: 8 months of OCaml after 8 years of Haskell in production (by @chshersh) I tried to provide a reasonable and balanced overview of these two languages, although my experience in both is OCaml versus Haskell. (Ruby has dynamic behavior and “developer friendliness”. Dec 25, 2005 · [Haskell-cafe] Haskell vs OCaml Branimir Maksimovic bmaxa at hotmail. F# has even worse value restriction rules than SML, let alone OCaml. Ocaml is also a lot easier to learn than Haskell. 😉 But I think I’m on to something… Haskell reminds me of Java, and even Ruby: it’s got a couple awesome features — strong static inferential typing plus purity. May 11, 2017 · Certain posts favor Haskell for pattern matching and simplicity of language, JVM based FP lang have a big advantage with respect to using existing java libraries. OCaml’s original (and default) “next-fit” allocating strategy is pretty simple: And yet, they threw away OCaml/SML-like module system. Apr 18, 2023 · This is a guide to Haskell vs OCaml. In particular, it's a parametrized module: a module that takes another module as an argument. Now some proponents of OCaml quite frequently complain about Haskell being slow compared to OCaml or F#. Aug 20, 2020 · So the Rust that I see today is supposably quite different from the Rust of 2010. 0). Jul 19, 2023 · One particularly attractive aspect of Haskell is its embrace of programming concepts like immutability, lazy evaluations and strict types. 12K subscribers in the ocaml community. But as the core languages of OCaml and Haskell are very much similar (except for lazy evaluation that is distracting for the beginner), it's easy to learn Haskell once you know the basics of OCaml. OCaml obviously has lots of features that Haskell and Erlang lack. LazyList and then Core. The thing to note about the implementation is that it uses coercions/constructors/pattern matches to wrap/unwrap the parametrized types IntSet a / IntList a to/from their monomorphic representations Set Int and [Int] . Similarly, Rust the language is quite pretty, syntax-wise. id foo . 1. It's already bound to blas/lapack, so you don't really have to do anything special there. Same thing. NET ecosystem. performance (time/space complexity), and the code is a bit clearer if you're coming in cold after not having seen parts of a codebase for a while. My complaint on this front in OCaml is mostly aesthetic. Published on December 6, 2019, last updated December 11, 2019 This is a comparison between the two languages by someone who has written code professionally in both. Plus leveraging . Same I was actually impressed by the memory use of haskell being comparable to Go (even in the worst case)! I've always thought one of the biggest drawbacks of Haskell was the memory usage patterns/leaks/etc (as well as laziness surprises), but compare that to OCaml and Haskell is doing quite well. Answer for the fastest 200 contributed programs —. Sequence, and in the end, I don’t think it was worth it. This article will compare OCaml's module system with Haskell's typ Jan 6, 2024 · I received tons of feedback on my OCaml vs Haskell blog post! Thanks a lot to all who read and shared their thoughts . " Here are my notes on OCaml vs. Modules in OCaml are my favorite part of the language and they seem to be unrivaled by other languages. yawaramin July 10, 2023, 2:55pm I love both Haskell and OCaml, and I have used them quite extensively. Version 4. Jun 2, 2009 · One thing to note here, is that Haskell's $ operator actually works more like F#'s <| than it does |>, typically in haskell you'd write the above function like this: third xs = head $ tail $ tail $ xs or perhaps even like third = head . 87 35,692 905 2. Coq is very easy: you know already which one you want to choose by looking at the type of your project. Mar 18, 2011 · Your dichotomy "Haskell vs. During my final term at UWaterloo I took the CS444 compilers class with a project to write a compiler from a substantial subset of Java to x86, in teams of up to three people with a language of the group’s choice. Previous message: [Haskell-cafe] Haskell vs OCaml Next message: [Haskell-cafe] Haskell vs OCaml Messages sorted by: I have a sense that when folks want to get into FP, they gravitate to Haskell as opposed to OCaml/ML (simplifying!). Sep 7, 2018 · I wrote this comment on r/haskell, and it’s not popular there. Meanwhile, OCaml is so ugly that the community came up with a whole other syntax for it. This page aims to cover some of its differences from Haskell. This suggests a serious problem with the benchmark. This article will compare these two languages, focusing on their syntax, type systems, performance, and c Go is focused on multitthreading while ocaml didn't even support it properly a couple of months ago. The most important reason people chose Haskell is: With this being a realtime application I'm naturally looking for the best performance I can get. 47 86% 66% Jul 7, 2023 · Hence, every OCaml 5 program can be introspected at runtime for interesting events using Olly. the ML world" is wrong¹. Over 10 years later I still think this is a advantage. Jan 7, 2024 · I received tons of feedback on my OCaml vs Haskell blog post! Thanks a lot to all who read and shared their thoughts .
