I don't understand what's wrong with the Nix language. Sure, the space-delimited lists can get a little annoying, but other than that it's minimalistic enough to use a configuration language but complex enough to do more complicated things like overriding derivations. Maybe it's because I learnt Haskell before Nix so the syntax is very familiar to me, whereas I see how it could be a learning curve for other users.

What I find the most annoying is the lack of documentation of some of the nixpkgs functions. Some of the functions provided by import <nixpkgs> {}.lib appear to be the same as the ones builtin to the Nix language and there doesn't seem to be any clear guidance on when to use which version. I've also had to look at the source code to find out the difference between writeTextFile, writeText, writeTextDir, writeScript, and writeScriptBin. [The docs][1] explain writeTextFile, but the only documentation for the rest is ‘Many more commands wrap writeTextFile including writeText, writeTextDir, writeScript, and writeScriptBin. These are convenience functions over writeTextFile.’.

Additionally, it's a bit frustrating for me how all the documentation for nixpkgs — the lib functions, how to make a derivation, specific details for building packages in certain languages, how to contribute to nixpkgs, overriding packages/overlays etc — are in [one gigantic web page][2] that's quite slow to load and even slower to search for things in.
