FWIW C++ does have a "pointer to member" feature. It looks like this

class Example {
public:
   void f( int );
};

// Declare p to be "pointer to member function of Example...
// Initialize p to point at Example::f.
void (Example::*p)( int ) = &Example::f;

Example object;  // Create an object.
object.*p(42);   // Invoke member f indirectly on 'object'
