I haven't compared the time, so this may be somewhere
where my intuition misleads me. I've have used it just
because a dict, because of non-duplicate keys, seemed
in some cases, a better mapping of sets than lists.
Since you don't require a key<->value mapping, (you're
just using a dict to take advantage of the hashing ) you
can make all the values null, or probably better, make the
value == key.
