Maybe not, but at least it will get people to stop for a bit. >The OP wanted to minimize memory usage, exactly the intended usage of >slots.

The whole point about warning against __slots__ is that you should never use them unless you are certain they're the best solution. Consider what happens when the OP wants to subclass this __slots__-using class. Avoiding __slots__ will almost never harm anyone, so I feel completely comfortable sticking with a blanket warning. -- Aahz ([EMAIL PROTECTED]) <*> http://www.pythoncraft.com/ "Typing is cheap.
