As far as I'm aware there is no way to do this in any of the standard 
libraries. This said, it is possible (at least to some extent), to do 
some runtime reflection by parsing symbols out of the object file and 
demangling them - this is what I'm using, but it's not as extensive as 
what you're requesting, it's very use specific (mainly missing calling 
methods with any number of parameters). It should be possible with some 
work though.
