[Hugs-users] [ANN] - Hugs for MacOS (x86) - via Nix Flakes

[Anthony D Clayden]

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.
