Currently, I can find the names of functions, classes and interfaces -
be they from an extension or userland code.

But I can't get namespaces, or their aliases.


I'm not totally sure of any other use. That's why I was asking.

As (or if) more extensions start to use namespaces to protect their
contents from name collision, we are probably going to have namespace
collision before long.
