Last week I did some work and updated twistedchecker

so that it uses pylint >= 2.4.4.  Before that, it was using a really old version

of pylint.

twistedchecker is run over the Twisted code as part of CI, and reports

various style issues.  Now that twistedchecker is using a newer pylint,

it should be compatible with newer Python language features.

Now that Twisted supports Python 3.5+ (with Python 2.7 support being dropped),

is it OK to start using newer features of the Python language in the Twisted codebase

such as type hints ( https://docs.python.org/3/library/typing.html )?

I don't have experience with that feature, but it looks like it could be useful,

when combined with a tool like mypy.  Does anyone else have opinions on

type hints and mypy?
