husk-scheme VS godot-haskell

Yes. One more -- the first (only?) Scheme written in Haskell, Husk, started in 2010 (which is the data of the commit for the first entry, "Initial version", in the Changelog)

Might be controversial? But I think an idea for one of the coolestsystems in my mind is a core engine in Haskell and Husk (R7RS Scheme) on top of it! You could write a verified core with a fun language on top for data, NPC scripting, etc. Sounds like a fun project, good luck!

It looks like there might already be something in the works for the existing godot-haskell package https://github.com/SimulaVR/godot-haskell/issues/39

You could also check out the Haskell bindings to the Godot game engine. Although Godot has it's own scripting language which tends to be easier to use for simple game development. If you have complex game logic that you want to implement in Haskell, you could go this route.

Although godot-haskell might be a way to go with that? https://github.com/SimulaVR/godot-haskell

I want to be able to use the hypothetical_function in my Godot game. I see that there is a way to use Haskell with Godot, but the documentation focuses on how to bind Haskell to Godot classes and things like that, which is not exactly what I need. I just need to use a function that is not aware about Godot at all, and I can't quite figure out how to do that. What would be the easiest way to implement this?

I've recently taken to the godot-haskell bindings. They're updated often and having access to a full engine for graphics, sound, networking, etc. is very useful. That being said, the bindings are fairly heavy handed, but once you get used to it they're not that bad. Not sure about performance, but Godot has bindings for Rust, Python, CLR, and Kotlin that can be used in tandem if needed.
