I am not entirely sure, but I suspect it is because you do not have control over what the increment, decrement, dereference, etc. operators do - you depend upon the pointer semantics. Instead, these should be defined specifically for each container class. This is certainly necessary for things like reverse_iterator, where the normal increment/decrement operations are reversed. Pointers only work in the trivial case as iterators. Even though late standards changes made sure that you could treat iterators LIKE pointers (ie. by using -> on them) they were never intended to BE pointers. Someone may have some more concrete reasons why pointers are truly evil, and not simply a hack until a proper implementation was completed. I could be entirely wrong here. Cheers, tim
