 - [ ] Closes #1663 

Note: I'm not sure how to test for this, as I think existing tests should be already failing due to this.  In fact, when I run `nosetests` on my system I get 123 skips, 29 errors and 2 failures, none of which are related to my addition, so there must be something wrong on my system.

I did not try the flake8 test and I think new documentation is exaggerated in this case.
