Using closures really hides them. Just think about this, I know a fellow programmer (A C fan), that used to pun another one (his best friend A C++ guru) - so the former used to have this: #define private public #define protected public This just shows how fragile the protection of member variables in C++ is (side effect of the pre-processor). After all, good C++ books recommend hiding data through other means (pointer that points to structure not published anywhere else (like in a library))
