Ah, so it does. I forgot about that. Most of my code has to run on multiple
versions (back to 2.4) and I remembered that set literals don't work:
[steve@ando ~]$ python2.6 -c "{1, 2, 3}"
File "<string>", line 1
{1, 2, 3}

It seems rather strange to argue that we should ignore performance when the
whole reason for using sets in the first place is for performance.
