I believe that's right -- go for it <wink>.

I think Python should say "l" isn't a valid identifier <0.5 wink>.

This *may* be a lot quicker:

def unique(L):
    return IITreeSet(L)

"It works", and so does IISet(L), but I'm not clear on the difference
between an IITreeSet and an IISet.  Maybe the latter is a one-bucket-only
gimmick (in which case its worse case for removing dups would be atrocious);
maybe not.
