Comment (by ncohen):
(and of course there is a way to do this without remembering "the list of
things you have already returned")
Or else, a bit easier, is to return the elements in lexicographical order.
It's less pretty, but easier to implement. And in this situation, you only
remember from each iterator the list of elements you have already used.
And you can "ask for another element" when needed.
Actually, this order of enumeration is more realistic.
I prefered the previous one, but it is trickier to enumerate :-P
