I much prefer GNU Guile over Nix. Anyone else? I saw some progress being made towards making NixOS compatible with other programming languages.
I'm in love with Scheme, so would much rather use Guile/Guix for this than learn Nix's DSL that's not even lispy and that's not used anywhere else.
These days those aren't the only options; you can also use Nickel: https://github.com/nickel-lang/nickel-nix
Which isn't fully baked, no, but here's hoping.
