Enforcing spaces in containers?

[DavHau]

I see that you once tried changing the behavior of nixpkgs-fmt to no space (nix-community/nixpkgs-fmt#280).
Any reason why you changed your mind?

In the equivalent discussion on nixpkgs-fmt, it seemed like everyone kind of agreed that it doesn't impact readability and just results in more horizontal space taken. Also it was shown that most code in nixpkgs uses no space (Not that I think this is important, but at least we know that not many people there are going to complain about spaces being removed).

I'm ready to go for:

• []
• [1]

• [
    1
    2
  ]
  

There is some stuff we haven't thought in a rational way about, are simple to implement, and would be awesome to do before the 1.0 release

Small example of what other languages do:

const x = [];
const x = [1];
const x = [1, 2];
const x = {};
const x = { a: b };
const x = { a: b, c: d };
