This is probably do to support 'foo.__get__(bar)' as an idiom. Let's make sure that the behavior is correct. Since we don't actually use the 'type' argument at all, this test calls it the idiomatic way to ensure that signature works; test_proxyInheritance verifies the how-Python-actually-calls-it signature. tSamplecBseZeZdZRS(cSs t|_dS(N(Rdtcalled(R ((sG/usr/lib/python2.7/dist-packages/twisted/python/test/test_components.pythellos(RRRcRR(((sG/usr/lib/python2.7/dist-packages/twisted/python/test/test_components.pyRsRRN(( RRt_ProxyDescriptorR:t__get__RR/t failUnlessR(R Rt fakeProxyt testObjecttpdtfakeClassMethod((sG/usr/lib/python2.7/dist-packages/twisted/python/test/test_components.pyttest_proxyDescriptorGets    csdttfdYdffdY}t}||}|j|jddddd d d |j|jd tddd d fgd S(s Subclasses of the class returned from L{proxyForInterface} should be able to upcall methods by reference to their superclass, as any normal Python class can. tYayableWrappercBseZdZRS(sI This class does not override any functionality.
