I had an idea for a moment about having sorted/reversed return the same 
type as it was passed -- so reversed(seq) returns a seq, 
reversed(iterator) returns an iterator. But it sounds confusing/magical 
and maybe out of line with Python philosophy. Although I think the whole 
iterator usage seems a little messy right now, so it's worth thinking 
about how seq/iterators-related functions should behave.
