The group wants to cut GHC's own CI turnaround time from 6 hours to 2, and aims for installation, documentation and tooling good enough that beginners never get stuck. Other goals include deterministic debugging tools instead of log dumping, a hardened software supply chain, faster security incident response, and asks whether 10-year-old Haskell code could be compiled with the latest GHC without source changes. The committee is seeking companies, contractors and volunteers to help execute these initiatives, and invites proposals and support for funding them. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How long does GHC's own CI take to run and what's the target turnaround time? GHC's own continuous integration currently has a turnaround time of around 6 hours. The Haskell Foundation's technical leadership committee has set a goal of bringing that down to 2 hours as part of a broader push to improve iteration speed across compilation, REPL use, dependency caching, and test integration. _Developers frustrated by slow Haskell build pipelines can follow this push on daily.dev as it develops._ ### What is the Haskell Foundation's technical leadership committee and what does it do? It is a newly bootstrapped group within the Haskell Foundation tasked with developing initiatives and proposals for the Haskell ecosystem that need funding and execution. It runs a lightweight community proposal process open to companies, contractors, and volunteers, with community comment and counter-proposals allowed when funding is involved. _Anyone weighing whether to contribute to Haskell tooling can track this committee's proposals on daily.dev._ ## Community take How the wider developer community reacted, aggregated from 2 discussions and 82 comments across hackernews, lobsters (as of 2026-11-13). **TL;DR:** Discussion of the Haskell Foundation's vision sprawled mostly into a tangential debate about whether strict, terse languages like Haskell are good fits for LLM-driven coding, alongside recurring gripes about fragmented tooling (ghcup/stack/nix/cabal), poor onboarding, and Haskell's lack of mainstream application domains. **Sentiment:** 25% positive · 45% mixed · 30% skeptical **The case for** - Some report Haskell generates code at least as well as other languages with LLMs and offers fast, localized feedback via ghci. - Several point out mature web frameworks (Yesod, Servant, IHP) and libraries already exist for GUI, embedded, GPU, and web use cases, contradicting claims of missing infrastructure. - One commenter credits Haskell's strict typing with making agent-assisted development more reliable at scale, citing a real-world CAD file tool built this way. **The pushback** - Many argue LLMs do much worse with strict, less-trained-on languages like Haskell because compile-error-fix loops burn huge amounts of tokens compared to Python/JS. - Multiple commenters say the installation/tooling story is genuinely confusing (ghcup vs stack vs cabal vs nix), undermining the 'Unix philosophy' framing in the vision. - Several feel Haskell lacks a clear practical niche or platform dominance, leaving it stuck as mostly a CLI/academic language versus Rust or Lean. - Beginner-friendliness is questioned, with one commenter struggling to parse a moderately complex type signature, though others pushed back that this reflects unfamiliarity rather than inherent difficulty. **By community** - hackernews (mixed): The thread mostly drifted into a long tangent about Haskell's suitability for AI-assisted coding, with genuine disagreement, plus recurring but contested complaints about tooling fragmentation and lack of real-world adoption. - lobsters (mixed): No comments were provided for this discussion, so no specific take can be drawn. **Hottest debate:** Whether strict, terse languages like Haskell are actually well-suited for LLM/agentic coding, or whether token-hungry compile-fix loops make them worse than mainstream dynamic languages. **Open questions** - Can Haskell achieve compilation times competitive with languages like Go given its semantics, especially incrementally? - Is there a realistic path for Haskell to gain a flagship application domain (GUI, games, web) the way Rust or JavaScript have? - Would better agent ergonomics (not just type-system strictness) meaningfully improve LLM productivity in Haskell? **Highlights** > > If I could have a vision for Haskell, it was for it to be useful. ... > Haskell surely needs good DX, but it also needs really better reasons for existing. Man am I tired of people dropping negative crap like this any time Haskell comes up, especially when they end up at the top of the comments. It ends up derailing most conversations about Haskell that aren't on explicitly Haskell-focused forums, and turns every post on Haskell elsewhere into a referendum on the language itself. FFS the post itself is explicitly about polishing up the technical infrastructure _to achieve what you're complaining Haskell doesn't have_ and all you can do is shit on Haskell in response: "We want to improve the developer experience!" You: "No one wants to use Haskell because the developer experience is so shit!" Put your money where your mouth is and do the polishing you're complaining about if you actually give a shit about Haskell. Fucking make something! Nothing is stopping you. Haskell is useful right now. I have personally been building a home automation system for it that uses Lua, MQTT, STM, and more that I have been running nonstop in my home for literally years now and it's absolutely awesome to work on and it's rock solid--partially because Haskell does an amazing job of helping me avoid bugs and provides a wonderful refactoring experience, which is a huge part of its reason for existing thank you very much. All comments like yours do is dissuade others from taking a look at the Haskell ecosystem by implying it's a pointless language; it steers people away, as the main takeaway is that you can't actually build stuff in Haskell and so why would you want to use a language that you can only build CLI apps in? (Absolute bullshit btw.) As someone that cares about Haskell and spends my time actually building stuff with it, I just read posts like this and shake my head. You absolutely can use Haskell to make things, and insofar as Haskell doesn't get used (distinct from being useless) and has a ton of sharp unpolished edges remaining, it's the fault of posts like yours as much as anything. Either get involved or give it a rest and go use the other languages you seem to prefer. You aren't treading new ground with this comment. Sorry to swear so much but that really pissed me off > — [ddellacosta on hackernews](https://news.ycombinator.com/item?id=50487663) > I've been generating probably 500k lines of Rust with all the SOTA models (and now DeepSeek). Every model does an absolutely horrible job generating good Rust code. You have to babysit it and you need to question everything the model spat out. I mean, free functions and no general nice trait/struct/enum based architecture, random `Mutex`/`RwLock` everywhere, all your big futures inside a `tokio::select!` etc. Yes it's great when you do your first Rust project. After a year it's a nightmare if you don't keep a clear control how the code is generated and organized. > — [pimeys on hackernews](https://news.ycombinator.com/item?id=50488199) > I do AI research and mostly work with Lean these days. I love Haskell, though I wouldn't consider myself a particularly strong Haskell programmer (just never spent a ton of time working in it). I think you're spiritually correct that there are lots of reasons to use extremely strict languages with AI, but the reality is a little messier than you'd expect. Token efficiency is specifically the place where strict languages get a little trickier. With dynamic languages where the model has a ton of training data, like Python, the agents are really good at writing code that just works. You still have challenges there, but they're just different than the challenges you hit with a language like Haskell/Lean/Agda etc. With Lean, for example, the amount that they agent might think it needs to prove for a relatively trivial operation can lead to an absurd amount of code. It sort of plays perfectly towards current agent weaknesses, where agents can run off and reinvent a lot of machinery and build unnecessarily complex abstractions. And those iterations have a cost. Even if the final artifact is more terse, the path to getting there can involve a huge amount of backtracking and rewriting and off-by-one syntactic corrections. Ultimately, a lot of this comes down to developer experience. Getting useful error messages for the agent, having fast compile times so that the agent can iterate quickly, providing useful utilities for debugging, etc. There was a popular blog post specifically about Haskell that generally makes this point--the Haskell language is, in a vacuum, ideal in a lot of ways for AI, but the Haskell developer experience and ecosystem made it hard for this team to build with it via agents: https://avi.press/posts/2026-07-10-after-7-years-in-producti... Note: I am not advocating against using these kinds of language. Obviously, I still work in Lean and a little in Agda and some related languages/projects, so I think this direction is right. Probably biased in that I love them with or without LLMs, but I do think they're also more ideal for AI development. There are still just challenges in getting agents productive in them, and most of the challenges are not about the type systems but the actual ergonomics and dev experience. > — [calebkaiser on hackernews · 3 comments](https://news.ycombinator.com/item?id=50487468) > There is this memo video of S. P. Jones that famously says "Haskell is Useless". I love Haskell, but I wished it was universal like C, C++, JavaScript, Rust, and C#. By that I mean: It could be used to create apps for desktop, mobile, and web. JavaScript can be used to do so many things like power the entire web, be on node and let anyone create cli and share the code with web, and mobile through React Native, on desktop with Electron and its alike things, it lets you do plugins for god knows how many things, it lets you write things for the GNOME Shell... C and C++ are perhaps behind everything in the world and string theory finally gets seen will see they are written in C. And they can be compiled to Web and almost everything in the world. Rust is a placeholder for the two, and C# reinvented itself when it saw Mono and now works even in the browser. Each time I see Haskell I wonder what else can I do rather than creating CLI apps, and it makes me choose something else that grants me more code reuse and interesting applications. If I could have a vision for Haskell, it was for it to be useful. Academic research and making compilers is cool, a few cli things here and there are cool too, but why can't we build music players and game engines and flutters and web pages with it? The language is way more elegant and beautiful than all the JS/C like languages out there and I really wished I could use it for the things I did. I'm aware of Servant/Yesod/IHP/Miso/Reflex for web, GTK/Monomer for desktop, TidalCycles for music, SDL/gloss for games, and various FFI/plugin, but none of them feel as coherent and worked on as the others, none of them are polished. Haskell surely needs good DX, but it also needs really better reasons for existing. > — [pmkary on hackernews · 8 comments](https://news.ycombinator.com/item?id=50485715) > > the onboarding experience of rust > we are going to build the best onboarding experience in the programming language ecosystem > This can only be done if we commit to unix principles > write programs that do one thing and do it well Rust is so approachable because Cargo does not subscribe to "do one thing". In fact Cargo does a bunch of things. Which is very convenient for newcomers, because they only need to learn one thing instead of a bunch (and how they interact). The same holds for a GUI like a file explorer with buttons and interactions like drag / drop or marquee select, which is a bunch simpler than chaining 3 programs together to delete 30 old files and move some folder into a subdirectory. It also explains why the most successful tools within the land of Unix philosophy are stuff like AWK, which really don't just do one thing. Or why PowerShell is less usable than GNU. Or why Emacs is an 'operating system'. It's also a reason why the installation experience for Haskell is so bad: there are a bunch of programs and users don't know where to start and what they need. > Cabal and Stack: which one should I install? > We recommend installing both. One thing and one thing well. Atleast it seems they've added a combined installer for these tools since the last time I've checked. > — [\_bent on hackernews · 1 comments](https://news.ycombinator.com/item?id=50485513) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=50484235) · 153 points · 82 comments - [lobsters](https://lobste.rs/s/xe0prv/technical_vision_for_haskell_ecosystem) · 13 points · 0 comments ## Similar posts on daily.dev - [Haskell ecosystem activities report: March–May 2026](https://daily.dev/posts/haskell-ecosystem-activities-report-march-may-2026-vfwpljwx5) · Planet Haskell · 0 upvotes · 0 comments - [Issue 501](https://daily.dev/posts/issue-501-fccp8qscy) · Haskell Weekly · 0 upvotes · 0 comments - [Enterprise Haskell at H-E-B](https://daily.dev/posts/enterprise-haskell-at-h-e-b-sjpe3tn1b) · Lobsters · 0 upvotes · 0 comments - [Haskell ecosystem activities report: December 2025–February 2026](https://daily.dev/posts/haskell-ecosystem-activities-report-december-2025-february-2026-dxnybmmbf) · Planet Haskell · 0 upvotes · 0 comments - [Issue 549](https://daily.dev/posts/issue-549-sb5llbgny) · Haskell Weekly · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#haskell](https://daily.dev/tags/haskell) [View this post on daily.dev](https://daily.dev/posts/a-technical-vision-for-the-haskell-ecosystem-vy0hywfpm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A technical vision for the Haskell ecosystem","url":"https://daily.dev/posts/a-technical-vision-for-the-haskell-ecosystem-vy0hywfpm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/a-technical-vision-for-the-haskell-ecosystem-vy0hywfpm"},"datePublished":"2026-11-13T18:22:54.381Z","dateModified":"2026-11-13T22:17:27.544Z","description":"The Haskell Foundation's technical leadership committee (TLC) has finished bootstrapping and published its vision for the ecosystem.
