[Interface-dev] About internal impelementation of zope.interface

[Deniz Kurucu]

Hi i'm trying to understand internal implementation of zope.interface. As
far as i understand 'implements' method patches the current class and
assigns to its __metaclass__ a method which is called when interpreter
encounters the class. After that it removes that fake metaclass and
restores its defaults. What i can not understand is what is the purpose of
method determineMetaclass in advice.py why just not get the first metaclass
in __bases__[0] ? Thanks in advance ...
