We had quite a bunch of changes in the past that added builtins to get them highlighted properly[1].
Nowadays it's possible to get this from Nix itself by running nix __dump-language. This was done on a recent Nix and includes all experimental features by default[2] which seems fine to me since this is not an LSP, but only an approximation.
This patch adds a few new builtins, e.g. break and flakeRefToString and a script to regenerate the list.
This doesn't include non-scoped builtins (e.g. map, baseNameOf etc.), but those are added far less frequent, so this seems OK to me.
Also, there are a few hidden builtins, most notably unsafe* and scopedImport. I think this was done on purpose by upstream and I'm wondering if we should adhere to that approach. If we still want to keep those, I think we should add those to a custom highlighting group that's maintained manually.
