Oh how I do love the docs at #NixOS.

I am attempting to do the "System wide vim/nvim configuration" example at https://nixos.wiki/wiki/Vim and rebuild is giving me this error:

error: attempt to call something which is not a function but a set

I read on one forum that removing the { } you see there, the set in question, from the override line, that would fix it, but then I of course get

error: expected a set but found a function

Since this is coming straight from the wiki and my syntax is correct, this is what you might call

Annoying
