Return a proxy object that delegates method calls to a parent or sibling

+ The *object-or-type* determines the :term:`method resolution order`

+ For example, if :attr:`~class.__mro__` of *object-or-type* is

+ The :attr:`~class.__mro__` attribute of the *object-or-type* lists the method
resolution search order used by both :func:`getattr` and :func:`super`. The
attribute is dynamic and can change whenever the inheritance hierarchy is
updated.
