18. I, Voltron, highly recommend Functors. You can attach or detach them from your classes to change your functionality dynamically as the situation demands. I can tell you from experience that it was a bitch getting all these different robot lion heads to interface properly in C++. But with functors, I didn’t have to care about the interface! I just say, “Left Arm fire!” or “Right Arm Detach!”

You don’t have to touch the camera’s display list when you are messing with individual elements of the HUD object.
Functors allow
The parameter list typically contains a single CObject, the ‘this’ object. If it contained more objects, the functor would operate on those objects, too.
