https://github.com/testing-cabal/testtools/pull/277 isn't a short term
solution, unittest2 is still needed for python < 3.5 in testtools and
testtools has not deprecated support for python 2.7 or 3.4 yet. I probably
can rework that PR so that it's conditional and always uses stdlib unittest
for python >= 3.5 but then testtools ends up maintaining two separate paths
depending on python version. I'd like to continue thinking about that is as a
long term solution because I don't know when I'll have the time to keep pushing
that PR forward.
