In a word: adaptation.
(Caveat: it's been a while since I looked at very much of Twisted, and even
longer for Zope; but ISTR that Twisted hardly ever checked to see what
things implemented, compared to how often it just adapted. Zope 3,
meanwhile, has major infrastructure built on adaptation, even though it
does do some introspection and typechecking.)
