You need to check your vision! Seriously, others have mentioned flat_set already, but the point is that using std::sort and the other algorithms is not reusable. You must use them, and use them correctly, every time you want the behavior, and you must be sure to use them at the right time. That's the essence of the need for a library: provide a reusable component for non-trivial functionality.
