Unfortunately, I'm unable to run tests locally b/c of severe dependency
hell. I am unable to get tox, detox, python setup.py test, and other
means of running tests to work at all. So, since I'm blocked on a
project by the lack of optional validator support, I am going to close
my eyes, look away, and pull the trigger, and hope I hit the target.
If someone who has a working Python configuration can please be kind
enough to let me know if my changes fail any tests, I'd be very
appreciative.
Even better, I'd love to know why a stock Python distribution with
dependencies installed is incapable of running the tests for attrs.
However, this isn't the right forum to answer that question.
