pypy3.5 support

[slocke716]

Why is this limited to only 3.6+ ? I'm unable to pip install with pypy3.5 so I installed with 3.7 and ran against the code written in 3.5 and all of my tests still pass. Are there specific known issues?

I would like to avoid forking and pushing to pip under a different name with only the setup.py altered but this tool would be amazing for my team.

You need python 3.6 to run black, but it can process any version of python code.

Because it takes advantage of useful language features (e.g. f-strings) available only in 3.6.

If you did that, you would find that the code does not run under 3.5. It's not just an arbitrary limit in setup.py.
