I think I am in the group of people who have no business using __slots__ ;-) What I gather from discussions on comp.lang.python is that really the only good reason for using __slots__ is for the memory optimization when you have huge numbers of objects instantiated. There are quite a few gotchas in the docs and more discussed in c.l.p. Search c.l.p for __slots__ to find discussion...
