Thanks for pointing that out. Information on it added in http://hg.python.org/peps/rev/b7979219f3cc#l1.7 +PyPy's RPython offers ``extendabletype`` [#pairtype]_, a metaclass which +enables classes to be externally extended. In combination with +``pairtype()`` and ``pair()`` factories, this offers a form of +single-dispatch generics. +..
