C++ is lame

Why isn't there a way to change context of a callee ?
In JS we could use Array.prototype.slice.call(arguments), but it seems that nobody has ever thought it could be usefull in c++ ...

To be honest, I've hoped that someone fed the troll by saying that it was possible (I hadn't found doc on a such feature before posting here).
I've failed.

But, to answer my own question, I've found it : pointers to members

Anyway, thanks >>2 for this funny sentence =]
