   If I understand what you're trying to do, I think the standard 
workaround for this it to override __setattr__ the way you want, and 
directly muck with __dict__ in __init__, e.g.

 >>> class C:
...   def __init__(self, stuff):
...      self.__dict__['stuff'] = stuff
...   def __setattr__(self, attr, val):
...      pass
 >>> c = C('1')
 >>> c.stuff
'1'
 >>> c.stuff = 2
 >>> c.stuff
'1'
