Consider this:


C:\Dokumente und Einstellungen\Administrator>python
Python 2.3a2 (#39, Feb 19 2003, 17:58:58) [MSC v.1200 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> class blah(object):
...   __slots__ = ['a','__dict__']
...
>>> a = blah()
>>> a.__dict__
{}
>>> a.b = 5
>>>

which of course is kina wierd....

Ciao Ulrich
