Consuming the iterator is *necessary* to get the last item. There's no way around that.

Obviously, you could itertools.tee() it first if you don't mind the cache space. But there cannot be a generic "jump to the end" of an iterator without being destructive.

That's no good, because it consumes the iterator. Yes, you get
the last value, but you actually needed to do work on all the
previous values too.
