Consider a class derived from an STL collection.
You should never do that.
Why not, why never? My opinions on this issue at:

While there are technical reasons not to do so (absence of virtual destructor), there are also non technical ones. It simply doesn't make sense to use inheritance for this. Inheritance is for polymorphism, not code reuse. This is why for example free functions that take any range are better than member functions.
