Note that possession or absence of a __dict__ attribute doesn't necessarily mean that you can or can't set attributes, as the class can override __setattr__(). Ultimately, there is no guaranteed mechanism to determine in advance whether or not an attempt to set an attribute will succeed. -- http://mail.python.org/mailman/listinfo/python-list
