Is this a riddle of some kind :-) I'm sorry Daryle, but I don't quite
understand. There is
one other name I have though of, smart containers, but that seems a bit
pop-smart.

Op( size_type n, const T& t );

not yet. There was some discussion on comp.lang.c++.moderated recently, but
I have not read up on it. If you do have a
ptr_container<size_type>, you will definitely get a ct error if something is
wrong. If you explicitly
cast the first argument to a size_type, the correct overload will be picked.
But I guess a small tag mechanism would do the trick.
