Well, you would use records, but records are a weak point of the Haskell language. I've discussed "why not Haskell" with some Nix people and they specifically mentioned the lack of row polymorphism.

You couldn't reasonably create a record for the NixOS configuration - the amount of options (fields) is massive. The all-packages.nix file is an untyped dictionary mapping strings to derivations as well.

Purescript?

Can I just point out that pretty much all of these options, including guix, are things that were invented well _after_ nix was established as its own thing?

(aside from Haskell and Scheme themselves, of course)

I don't think you need to worry, I'm sure that who's familiar with PureScript also knows it's more recent than Nix.

Those PureScript records tho...

Purescript cannot type a record merge or join. Haskell with type families can, but the syntax would not be very pretty.
