I will point out that in the transition from 2.3 to 2.4 our code that uses sets has

try:
    x = set
except NameError:
    from sets import Set as set
else:
    del x

Rather ugly. I suppose I could just put the necessary incantation in sitecustomize to dump the set name in builtins, but it would be kinda nice if this sort of thing could be avoided in the future.
