add_child() is responsible for reporting errors about type, value, and
module duplicate definitions. Although it checks for all three, it uses
namespace_to_str() to convert a Namespace value into a string before
printing an error like:
error: duplicate definition of type `foo`
^^^^
note: first definition of type foo here:
^^^^
Unfortunately, this string can only be one of "type" or
"value" (corresponding to TypeNS and ValueNS respectively), and it
reports duplicate modules as duplicate types.
To alleviate the problem, define a special NamespaceError enum to define
more specialized errors, and use it instead of attempting to reuse the
Namespace enum.
