[Zope] inheritance in python product

[Stefan H. Holek]

All your classes are derived from ExtensionClass.Base. The problem is to 
call __init__() of a plain (non-EC) base class.

However, what I have posted before works for me:

>>> from ExtensionClass import Base
>>>
>>> class Spam:
...     def __init__(self, name):
...         self.name = name
...
>>> class ECSpam(Base, Spam):
...     def __init__(self, name, color):
...         Spam.__dict__['__init__'](self, name)
...         self.color = color
...
>>> spam = ECSpam('fred', 'blue')
>>> spam.name
'fred'
>>> spam.color
'blue'
>>>
