Expand description
Coerce a Nix Value to a plain path, e.g. in order to access the
file it points to via either builtins.toPath
or an impure
builtin. This coercion can never be performed in a Nix program
without using builtins (i.e. the trick path: /. + path
to
convert from a string to a path wouldn’t hit this code).
This operation doesn’t import a Nix path value into the store.
