oh can it? I read it as meaning the tuple-things can be returned in any
order so you here you can process the two tuples in either order, but
each returns ('a','b') (in that order) so putting that together you get
you read it as saying that an unordered flwor can re-order the entire
returned sequence arbitrarily. Hmm perhaps the spec should make that
clearer (one way or the other).
