//I want
//A->functio();
}

I would strongly recommend against doing this. If you are working in the C++ world, you should expect to work with both pointers and references. Do not try to confuse the two!

The key difference between a pointer and a reference is the implied persistance. A pointer can take a NULL (or uninitialized) value, while a reference can not. If you overload the pointer operator, you have the potential for a reference to an unknown memory area.

Use pointers where necessary, expect others to understand them, and don't try to hide the fact that a pointer is being used.
