Aahz is, of course, correct. The reason I thought you needed __eq__ was 
because I was using a str subclass that I had created. I'd adapted it from 
something that been posted here. It had __cmp__ defined, but not __eq__,
and I got _interesting_ results when I tried to use it as dict key. You do 
need _eq_ if your parent class defines __eq_.
