These look good - many thanks!

Let's merge it and have lots of little PR's instead of one big one. BTW there is a small grammar typo in a comment I made that I am going to correct after merge.

This was before i read test_pyenvlib.py file which you ignore tests. but the file was
~/.pyenv/versions/3.7.3/lib/python3.7/test/__pycache__/test_enum.cpython-37.opt-2.pyc. I didn't investigate further.
