it's not wrong, but I find that many people use tuples in situations
where they should really use lists, and the immutability is
irrelevant.  Using tuples seems to be a reflex for some people because
creating a tuple saves a microsecond or so.  That sounds like the
wrong thing to let inform your reflexes...
