Reimplement namespaced identifier to support polymorphic args
This is somewhat of a temporary hack, as a namespaced identifier should
not really refer to types or polymorphic arguments. But we need a
tokenizer and a prepass to properly distinguish identifiers from types.
So it works, but error messages may be cryptic.
