I'm the upstream developer of padme -- the mostly transparent proxy class for Python. While working on unit tests for proxying numeric methods I realized that there are a few bugs in the mock library.

The bug I'd like to report now is that __rdivmod__ cannot be mocked by MagicMock. This seems to be caused by the fact that it is listed as magic but not as numeric (for which right-hand-side variants are created).

Note that it cannot be simply added to numeric as it doesn't have the augmented assignment variant (there is no __idivmod__).

The bug is present in all versions of Python that come with unittest.mock (3.3, 3.4 and 3.5) and it is also present in the upstream/standalone version of mock

I wrote a small patch and a test for it. Tested it on Python 3.5 and it worked.
