I don't like the design of C++ STL here. Instead of a
next_permutation(), what about ranges that yield all permutations, all
adjacent permutations, all combinations?

I agree that that's better conceptually, but your implementations have
overflow issues. (And it is not too obvious how to fix that, given the
existing range design.)
