Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

There is No “Tooling Issue” in Haskell
Significant effort is going into resolving this issue right now and things should be much improved in 9.6. We already have https://errors.haskell.org/ which catalogues many errors with descriptions and examples. The asspciated error codes will be added to all errors once 9.6 is release for easy reference.

[ANN] GHCup-0.1.19.0 released
We're also delighted to announce integration with errors.haskell.org, which already has a couple of GHCup codes documented, e.g. https://errors.haskell.org/messages/GHCup-00010/

[ANN] First release candidate for stack-2.9.3
To support the Haskell Foundation’s Haskell Error Index initiative, all Stack error messages generated by Stack itself begin with an unique code in the form [S-nnnn], where nnnn is a four-digit number.

What prevents Haskell from having good error messages?
I don't think the resolved issues are actually ones about error messages. They largely seem to be meta issues about the project. As far as I know nothing that project has done has made it into a released GHC yet, but GHC 9.6 will have unique error codes for each error pointing to an entry on https://errors.haskell.org/. Both the codes and the website are achievements of that project, specifically under its error-messages-index incarnation. If you'd like to contribute you may like to read https://github.com/haskellfoundation/error-message-index/blob/main/CONTRIBUTING.md or post a message introducing yourself on https://github.com/haskell/error-messages/issues/new.

There is No “Tooling Issue” in Haskell
You can use GHCI's debugger through Emacs's haskell-debug-mode (part of the haskell-mode package), and probably through other editor/IDEs as well, a programming editor like Emacs or Vim simply needs to be able to run a GHCI session and send commands to it.

Kill until next char preceding space | Uppercase | underscore
No, I was only using haskell-mode. So I guess this is LSP's fault, then. Not Emacs's fault and not haskell-mode's fault.

What’s so great about functional programming anyway?
If I made it sound like there's something like IntelliSense today, apologies! We've got <https://github.com/haskell/haskell-mode/blob/master/haskell-...>, but it's type-a-command-and-do-a-search: it's not linked in with completion directly in the setups I've seen.
(In practice, I'm usually starting from a slightly different place: I know I want a Frob and I've got a This and a That, so I do :hoogle This -> That -> Frob and get some options. The thought-process is working backwards from the goal more than forwards from one key object in focus. A different way of working, but I'm not convinced it's less effective.)
My point though was that it's an engineering issue, not a fundamental language limitation. ie not a reason all future languages should shun haskell features. The building blocks to do better at completion than haskell curently does are there.

Emacs becomes extremely sluggish when I enter a haskell file
check if you have any similar config to what caused this issue: https://github.com/haskell/haskell-mode/issues/1777 for me

Requests for packages to add to NonGNU ELPA?
Package-lint has been on my list, but the maintainer, MELPA's Steve Purcell, has been hesitant about NonGNU ELPA in the past (see this discussion), so I have skipped his packages for now, and also because most of the packages he maintains have a "broken" version tag, most of the time -- the reason here is that MELPA adds these manually, and since he understandably is targetting MELPA, there is little interest from his side to fix that.

Artyom's Haskell toolbox — a long list of tools/libraries I use
I use haskell-mode. It has a shortcut for loading a module into REPL, and it also runs hasktags for me. That's literally all I use.

My setup for messing about with Haskell scripts, 2021 edition
Just as a note from my poking around, this is the "official" way to use a nix-shell with haskell-mode: https://github.com/haskell/haskell-mode/blob/3a019e65b504861d7ea23afbfecd14e5ef63e846/haskell-customize.el#L77
