I'm so far behind on these, but it's rare that I see a lanugage I've never heard before. I've heard of scheme. How did you come to using this language for the challenges?

[–] vole@lemmy.world 2 points 3 weeks ago

I wanted to learn scheme and perhaps work through SICP. Guille seemed like a reasonable scheme to choose because I've also been considering learning Guix. Guix is a package manager similar to Nix, and it uses Guille as its configuration language.
