A similar implementation of a large subset of Haskell was done by Ben Lynn in a winning IOCCC entry as described at [1]. The graph reduction engine is the small C programs shown in [2]. A much larger and more production-ready implementation of Haskell into combinatory logic was made by Lennart Augustsson [3].

Huh, so it's not giving you full Haskell, but restricted to an API of under 300 functions: https://chrisdone.github.io/hell/api/ Interesting. I guess that's what made this bit possible: It was easy at the start of this project in early 2024 to say I like reading the code, because I was the only user. Now, after reading the code of a few colleagues, I still find it very easy to read the code. ie. you don't have to start hoogling library functions to read a new script (while having more sane behaviour than bash). My main issue with Yet Another Scripting Language is that you have to install it to new systems and you'll find some dependency issue with idunno glibc being the wrong version or arm vs intel etc. (Case in point: https://github.com/chrisdone/hell/releases only has hell-linux-x86-64bit ) I wonder, could you use
Read the rest
this with https://github.com/augustss/MicroHs ? They seem like a good combination, MicroHs being extremely portable, Hell having a restricted API and presumably quite stable dependencies. ----- (btw footnote 3 is footnote 1 again)
