Good idea, sounds right. And in case it did turn out to be
problematic, we could still go the way of adding all as keywords

Sounds good to me, the bitwise operations will be great to have, too.

Just one more thing still: I'm actually feeling pretty strongly
against having multiple different operators for the same operation
(set union, set addition/removal). I just see that as leading to
confusion: scripts will inconsistently use on or the other, people
will have different preferences which version to prefer; they may not
even remember the other one. And we'd end up having to explain why
there are two versions, without having much of a great explanation
("one is ugly" doesn't sound great to me :-). Is it just me feeling
that way?
