 ## Why native language?
 
 - Easier portability
+- Syntax highlighting and robust checking without needing to realize derivation
 - Nix can read from [JSON](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-fromJSON),
 [TOML](https://nixos.org/manual/nix/stable/release-notes/rl-2.6.html#release-26-2022-01-24).
 - We have also managed to hack together a [fromYaml](./../nix-conf/lib/serde/default.nix),
 though it will not work for strictly pure builds or bootstrapping builds.
