I can say the same about my knowledge of .NET reflection.

I've not heard of anythink like that, besides, I've not seen the need.

RTTI-returned string is (a) implementation-specific and (b) not guaranteed
to have any meaningful content. And, no, there is no mechanism in the
language to identify types by name during run-time. Generally, one can
say that there are no types during run-time.

Yes, you probably are. If you really need that thing, that is.

Similarly, there is no language mechanism to do that. You need to provide
one if you need it.

Ask in a GNU newsgroup.
