They are highlighted incorrectly as they are not currently valid Nix
code

Before:
```
[ inherit (attrs) a b c; ] := builtins.attrValues { inherit (attrs) a b c; }
```

After:
```
[ inherit (attrs) a b c; ] := [ attrs.a attrs.b attrs.c ];
```

The previous desugaring has some potentially nice properties such as
non-significant ordering and no-duplicate enforcement, but was
ultimately deemed unintuitive and too surprising in practical use.

The new syntax is

```
attrs.[ a b c ]
```

as sugar for

```
[ attrs.a attrs.b attrs.c ]
```

An overview of alternatives and their drawbacks (including drawbacks to
the syntax currently proposed) are provided in tables in the
Alternatives section, as requested by the Nix team.

These tables are intended to be an overview of some of the discussion in
this RFC and will be updated as discussion continues.
