You really don't want to do that. Then, if pb.Referenceable ever does
become a new-style class (for example because a new version of python
gets rid of oldstyle classes, or because twisted is changed), then
you'll get an MRO construction error. Always put object last in the
class Foo: pass
class Bar(object, Foo): pass # Fine
class Foo(object): pass
class Bar(object, Foo): pass # BOOM
