_ProxyDescriptor's __get__ method should return the appropriate
attribute of its argument's 'original' attribute if it is invoked with
an object. If it is invoked with None, it should return a false
class-method emulator instead.
For some reason, Python's documentation recommends to define
descriptors' __get__ methods with the 'type' parameter as optional,
despite the fact that Python itself never actually calls the descriptor
that way. 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.
