can it though? (or should it?) -- the fact is that it was decided the 2 and
2.0 are equivalent as members of a set (which makes great sense, there are
they SAME number, and the difference is an implementation detail), so the
answer to:
2.0 in {2}
and
2 in {2.0}
is True
I've lost track, but the answer to
a_set.add_unique(2)
should always be the same as
a_set.add_unique(2.0)
for the same set.
