Works quite nicely for flipping through PDF slides.

There’s a fairly active community over on Zulip [1] if you like to drop by for a chat or get some help.

For more on concurrency and parallelism in Haskell, check out Parallel and Concurrent Programming in Haskell [0], deemed as the best book on the subject, also written by Simon Marlow.

While so far the focus has mostly been on implementing the expression language as is, hnix being written in Haskell could be attractive for enriching the language with fancier features:

"Because now that it's in Haskell, now that a lot of other hackers could get involved, we could do things like add optional typing to the Nix language." — J. Wiegley

For more on hnix check out Haskell Cast's Episode 13 [1] with John Wiegley.

There was actually a thread on /r/haskell a few months ago [0] in response to an HN comment. In that thread, a few libraries were mentioned as examples of having amazing docs.

For instance, Gabriel Gonzalez writes a Tutorial module for his libraries, which introduces the basics of the library and shows you the big picture. The tutorial walks you through different pieces of the library, how to use them, and how they come together.

It's hands down one of the most effective ways of documenting I've ever seen and I'd love to see other communities' take on it.

To point out a specific example, you should check out Turtle's tutorial [1].
