@AnneGilles thanks for reporting! I still haven't had the time to try (I didn't even know!) flake8 3.0.

If you have the skills, would you mind providing a pull request? If not it will take a while as I will on vacations for a few days

@AnneGilles @danpalmer 2.0 release is out, please give it a try!

@gforcada works for us (as in: gets selected by buildout and installed, seems to do its job: I have not introduced unordered imports to actually trigger it) with latest flake8 3.0.4. Thanks!
