Comment (by SimonKing):
At some point, I need to find out what class the default implementation is
defined for, so that one can get the non-default implementation by a call
to `super`. That's a problem. Currently, I go up the class hierarchy and
test whether the conditionally_defined instance is in the `__dict__` of
the class. But if the conditionally_defined instance is wrapped in a
different wrapper (e.g., a cached_method), then this way of determining
the class will fail.
I wonder if Python gives this information automatically, when it invokes
`__get__`. To be investigated...
