Yeah the confusing thing is that omitting the docstring fixes it -- the class still has a doc attribute but apparently it comes from the metaclass. :-)

I guess you could have both a class and an instance doc by making a really clever descriptor, but it seems simpler to just use a comment instead of a docstring. :-)

I'll do this now.

Because somehow you can't have a slot named doc and a docstring in the class. Try it. (I tried to work around this but didn't get very far.) That's true for all class attributes. You can't have a slot and a class attribute at the same time. After all the doc string is stored in a class attribute, too.

class Example: ... slots = ("egg",) ... # This doesn't work ... egg = None ... Traceback (most recent call last): File "", line 1, in ValueError: 'egg' in slots conflicts with class variable

class Example: ... """doc""" ... slots = ("doc",) ... Traceback (most recent call last): File "", line 1, in ValueError: 'doc' in slots conflicts with class variable
