TypeInfo manipulation

[Zhenya]

Hi!
Tell me please,are any TypeInfo/typeid/classinfo manipulations 
possible?
For example I need a struct that overload typeid, or something 
like that?

Some time ago I tried to write some smart pointer that overlad 
classinfo property  in accordance with the real type of hold 
object,but I failed to do this becouse of
not having possibility to declar static and non-static version of 
the one function.Maybe there are better ways to do this?
