> pylint 2.4 provides a number of new features and fixes, but the most
> important/pressing one for me is that 2.4 adds support for understanding
> python type annotations, which fixes a bunch of spurious unused import errors
> in the PR I'm working on for BEAM-7746.
> As of 2.0, pylint dropped support for running tests in python2, so to make
> the upgrade we have to move our lint jobs to python3. Doing so will put
> pylint into "python3-mode" and there is not an option to run in
> python2-compatible mode. That said, the beam code is intended to be python3
> compatible, so in practice, performing a python3 lint on the Beam code-base
> is perfectly safe. The primary risk of doing this is that someone introduces
> a python-3 only change that breaks python2, but these would largely be syntax
> errors that would be immediately caught by the unit and integration tests.
