I could go on and write you novels about it, and if someone really wants to know I can provide a massively detailed, exhaustive list with logs, screenshots, Github issues, etc.
But sweet jesus, you'd think in 2021 a basic tenet of a language would be:
"I want autocomplete + hover-docs to work on a project which has +50 dependency libraries and several hundred files."
The language may be the best thing since sliced bread, but the tooling/ecosystem and authorship process is absolutely the worst thing I've ever touched.
Here's a particularly funny one:

Even "experimental" languages like Nim and Zig had a more reliable and easier to use tooling and IDE integration than Haskell did (for me), despite Haskell being ~31 years old.
> Not sure why you'd take that attitude though, really not a great way to get across whatever point you think you have
I guess to fail to understand how if the language is as fantastic as it's made out to be, why there's no equivalent to rust-analyzer or Eclipse jdt.ls and it can't build my company's 50MB binary in less than half an hour. And why is this state of affairs tolerated for decades?
Pascal/Delphi had an IDE and Dev UX that, according to programmers old enough to have used it, surpasses the productivity of most modern tools. And it is capable of compiling a billion lines of code in a couple of minutes.

So what is up with Haskell?
"Ymmv I guess" isn't what I would call a sound approach to core language tooling.
> other than that you can rant.
Unless someone wants to. Then I can dump a wall of particular things that are broken.
See: "and if someone really wants to know I can provide a massively detailed, exhaustive list with logs, screenshots, Github issues, etc."
You fail to understand that this is your personal experience based on the approaches you've chosen to apply.
I have no problems with HLS, VC Code, and Cabal, everything works seamlessly. I use Nix to bootstrap everything, I split my software into smaller packages so that I benefit from distributed, incremental, and cached Nix builds, and my statically linked binaries rarely exceed 10 Mib after UPX. I couldn't care less whether it's part of Haskell distribution, because the same language-independent toolchain I use in several different stacks works for GHC too. I'd rather let GHC maintainers work on compiler and language features than expected them to re-invent Nix functionality for the sake of it being part of the compiler distribution.

Sometimes you don't get to make the choices, and you're stuck with someone else's architecture decisions and a team + community of people doing the best they can with them.
You've never compiled GHC from source? How long does that take on your machine?
The moment someone gets a codebase that has hundreds/thousands of files working with proper language server diagnostics in an IDE with +24 hours uptime (like every other production-grade language) I will eat my shoe.
I have, but the point is that I don't have to, because there are transparent distributed builds in Nix that I utilise when I want to compile something big, as you say "real-world", fast. I split software into many small self-contained packages and delegate the work of compiling it all to remote machines configured for faster compilation times, and then I just pull complete binaries onto my laptop (https://nixos.org/manual/nix/unstable/advanced-topics/distri...). Subsequent changes in smaller packages are rebuilt incrementally.
My point and the answer to your question ("And why is this state of affairs tolerated for decades?") is that GHC doesn't have to implement its own version of dev environment bootstrapping, distributed builds and other niceties as part of their core tooling, because it's already solved on other level of dev-infra tooling, they can just provide links to working solutions and explain them, for instance haskell.nix (https://github.com/input-output-hk/haskell.nix)
that's not true, at least not in a larger context of available languages. There are C, C++, and a few other emerging language environments such as Mercury and ATS that can benefit from the same Nix toolchain right now, and their maintainers don't have to re-invent the wheel of packaging and distribution, as Nix solves that for them in a generic way.
> is basically a way to confirm "This language has some of the worst tooling I've ever encountered in my life."
For that you need to define criteria that allow you to identify the "worst" example. It is going to be the worst if you expect a monolith all-included distribution that has its own implementation of the same generic dev tooling approach (reproducibility, tracking of dependency sources, versioning etc), such as Rust Cargo or Go Modules. But these criteria won't match with the world where I see every software component to be a generic build instruction that Nix manages to provide regardless of the underlying language compiler.
Fair point, though Haskell seem to be the only language where Nix is the accepted solution to packaging and distribution.

That's a reasonable point of view to have if you already know Nix. Most people don't, so they see Nix as Haskell-specific, except it's not and you now have to learn a general tool which usually takes way more time than learning Cargo or Go modules.
The point is that embracing Nix makes the learning curve of Haskell way steeper currently, especially when you also have GHC, Stack and Cabal. Maybe it will pay off in a few years when everyone uses Nix, but that's not the case today.
Indeed it is, and learning more about users' experiences based on the approaches they've chosen to apply will help us make Haskell tooling more reliable in the future. These kinds of experience reports should be encouraged so that we can address the difficulties that they explain!
sure, my reply to OP was an experience report too, where I feel confused that people are still struggling with topics I've almost never experienced since after switching to Nix. They suggest it's a fault on GHC side, I suggest it's not a fault on GHC side, as there's already a solution implemented on another level of dev tooling that covers the mentioned issues (bootstrapping, discoverability, (re-)compilation times, binary sizes) for GHC in a true generic Unix way.
Thank you for yours too. I'm glad you're having a good experience with GHC and Nix. I haven't taken the Nix plunge yet!
GHC's compilation speed is in the same category as G++, which isn't great, but we users are mostly used to it, and deal with it by standard methods like separate compilation.
Some of the other issues you mention (such as crashes) are more significant, while some (IDE integration) are mostly a matter of the hardcore users not caring that much. I'm not that hardcore myself, but I was satisfied with Emacs Haskell mode until it broke a few releases ago, and even now it's fine for editing Haskell code, just not for running it inside the editor.
OCaml is at a good spot between Pascal and Haskell for that. Compared to Haskell, I find the tooling easier to understand but maybe not easier to use at first.
I wonder if this is really true. If it is, why wouldn't people use it?
Hello, yes, I really want to know! I am on the board of the Haskell Foundation and improving developer tooling is likely to be one of our focus points in the near future. User experience reports will help us make progress. My email address is in my profile (https://news.ycombinator.com/user?id=tome).
Will genuinely take you up on this, and try to condense things into an easy-to-read list =)
Tbf I think things are worse now than a few years ago because of the explosion of new Haskell code, plus the resulting several somewhat conflicting re-imaginings of the tooling to deal the increased complexity of juggling the now-huge code corpus. Stack, the original cabal, the current different cabal, Haskell Platform, etc. I like to think the vigorous activity in this area is not entirely unhealthy, since it is about identifying and attacking real problems. But, for those of us not in the middle of it and just want something that works, it is somewhat painful.
Tome, I can write up some issues and email them to you, but basically we need a better out-of-box experience. "stack ghci" takes so long to start up on an HDD server (tons of stuff getting paged in) that I keep thinking it has simply hung, while the old ghci was nowhere near that slow. Emacs Haskell mode goes into some crazy error loop if you try to use a ghci subprocess window (that used to work great). Haskell Platform (a blessed set of packages, more or less) was a good idea in principle but I think it became unmanageable and stopped being maintained.
I haven't done anything with Haskell in a while and this kind of thing is the main obstacle. Command-line ghc (ok, stack ghc) still works so it is still possible to compile stuff less conveniently when required. Mostly though, I just use other languages. If I were using Haskell for daily work then I could probably reach some reasonable tooling setup with enough effort, but as an occasional user it just hasn't been worth it.
