Oh well, judging by the responses, I guess it's not all that sensible
after all.

I just don't like typing "include?" for something as simple as a lookup,
especially when Set (to my mind) is just a special case of Hash --
with a bit more thrown in.  Also since "include?" is bad grammar.

Another question, then.  Why does Set#| return a Set, but Set#&
returns an Array?
