For a call-back mechanism, I want to store the address of a non-static
class member function. Turbo-C++ does not allow this ("member function
pointers are not true pointer types, and do not refer to any particular
instance of a class"). 

What does ANSI-C++ say about this? Are C++ implementations free to 
decide whether addresses of member functions are normal addresses?
If so, what do other C++ implementations decide? 

Anyway, could ANSI-C++ be extended with a new kind of "access specifier"
for a member function so that one can take the address of it?
