Something like this could go into the 'inspect' module (didn't even
worry about __slots__)::

  def find_def(meth):
    for cls in meth.im_class.mro():
        if meth.im_func.__name__ in cls.__dict__:
            return cls
    else:
        return None

For such a simple addition to inspect you just need a patch that has a
good implementation, thorough unit tests, and a core developer who
thinks it is worthwhile enough to add the functionality.
