zope.testing uses the attribute '__bases__' to store the information what the base layers are. __*__ are supposedly Python internal attributes. Specifically __bases__ is known to be used to store information which base classes a class has.
This sort of misdirection has, unfortunately, a long history in Zope 3 (and the various things that's become). Witness __name__. (There are others, but most aren't *actually* used by Python implementations.) Removing existing __*__ name ("underware") usage is probably untenable, but I hope we can avoid extending our foolishness. -Fred -- Fred L.
