* Add support for the new matrix multiplication operator `.
* Make ``__nonzero__()`` and ``__unicode__()`` exlusive to Python 2.x.

* Make ``__length_hint()`` exclusive to Python 3.4.
* Add support for the ``__cmp__()`` method, exclusive to Python 2.x.
* Add support for accessing the proxied object with the new
:meth:`~padme.proxy.original()` function.
* Add support for accessing proxy state with the new
