Thank you Justin,

You might not be aware of https://github.com/FranklinChen/hugs98-plus-Sep2006 — a repository for compiling Hugs. I believe Franklin was fixing a number of places where Hugs had bitrotted/no longer complied with FFI and other low-level interactions.

As to “use cases for Hugs”: I find it possible to modify the compiler, to give behaviour I’ve always wanted for Haskell. (I won’t say that’s ‘easy’, but possible compared to GHC — which I find impenetrable.)

See my occasional posts on Hugs-users for what I’ve been touching. It’s needed surprisingly tight-focussed code changes to deliver what GHC hasn’t got round to since ~1998.

I spent some time with the last public release of the Hugs sources,
making them compile on a modern Mac (x86 chipset). I used Nix's flakes
feature to manage the build and install.

If you'd like to run the hugs interpreter directly using the flake, just type:

`nix run github:m4dc4p/hugs#hugs`

If you'd like to execute a Haskell file, try:

`nix run github:m4dc4p/hugs <file.hs>`

Or alternately:

`nix run github:m4dc4p/hugs#runhugs <file.hs>`

(That is, `runhugs` is the default app provided by the flake.)

See the README at https://github.com/m4dc4p/hugs for more details
(including other binaries available).

I don't have much of a use case for Hugs, so I got the flake to the
point where I could start the interpreter and run simple programs. I'm
glad to accept pull requests or bug reports. You can find the source
and submit any issues at https://github.com/m4dc4p/hugs.

Note: I don't have access to Apple silicon, so this build has only
been tested under x86. If it works for M1 please let me know, or if
you are able to submit a PR I'd welcome it!

Enjoy!

Justin
