The compile-time reflection capabilities of C++ are impressive, but
still quite limited. For example, I'd like to be able to find out
about all of the members and member functions of a class, and all of
the free functions declared in a namespace.

Heh. typeof would be nice but it barely scratches the surface of
the possible and missing reflective capabilities.

Sounds like a great idea to me.
