One of the things that bother me about end-line comments is that this is
going to blow up line length limits. I think this could work if such
pragma comments could apply to the following line, and multiline pragmas
would be acceptable. Then you could have something like:
# flake8: disable=unused-import
# mypy: alias=pathlib2.Path
# coverage: ignore=when>py2.7

Hah. One of the things I never imagined was that folks would throw
around numeric PEP numbers and just expect everyone to have PEP 0
tattooed to the back of their eyelids. Quick, let's discuss PEP 3128!
