So what's the result if you pass in an iterable of length 1?
I *think* (from eyeballing -- I'm too lazy to type it in and try it ;) )
that it will return True, and it seems to me that that is probably the
correct behavior (especially if it's correct for a zero-length
iterable), but it's a corner case that probably deserves some mention.
