this seems weird to me, i know you cant overload normal functions in C++ based 
solely on return types, does this compile? and what happens if i dont use the 
return type on a call to f() on an instance of B ?

B instance;
instance.f();

what happens if i have a pointer to a B, but declared as type A and call f 
without using the return type?

A *instance;
instance = new B;
instance->f();

just curious :)

thanks,
