Because ... how to be polite about this? No, I can't. std::set is
crap. The implementation is a sorted sequence -- if you're lucky,
this is a heap or a C array, and you've got O(log n) performance.
But the real killer is that requirement for a std::set<T> is that
T::operator< exists. Which means, for instance, that you can't
have a set of complex numbers....
