[Twisted-Python] Interface Inheritance (Ha ha METACLASS)

[Jp Calderone]

    from twisted.python.components import Interface

    class InterfaceImplementor(type):
        def __new__(klass, name, bases, dict):
            realBases = []
            faceBases = []
            for b in bases:
                if isinstance(b, Interface):
                    faceBases.append(b)
                elif hasattr(b, '__implements__'):
                    faceBases.extend(b.__implements__)
                else:
                    realBases.append(b)
            dict['__implement__'] = tuple(faceBases)
            return type.__new__(klass, name, realBases, dict)
