pynvim Drop support for Python 2 and 3.4 (type annotations)?

I'm looking into adding type annotations, and would like to do this for Python 3.5+ then.

Both Python 2 and 3.4 are EOL by now, and it might take time anyway to merge type annotations then anyway.

What do you think?

Dropping support for python 2 on master is fine. We could create a separate maintenance branch for bug-fixes only on top of 0.4.0 (or whatever the last python 2 version)

Ok, what about Python 3.4?

Same thing there, python 3.4 can stay on 0.4.0/maintenance branch (if anyone still uses it). Lets move master forward.

Cool. No need to do this already, but good to know how to proceed in this regard.

Would you be able to accept help doing this if it were to be delivered module-by-module? If so is there any particular order to follow?

@noelevans I think "removing support" is not a goal, but should be done when it gets into the way somewhere. Then it is as easy as removing the classifiers and CI config, so it's not really a task by itself.

Alternatively, if python2 support is desirable so as to not phase out support for entirely for type annotations, typing is a pip installable library on python<3.5.

So we could add it as an install_requirement in the setup.py if sys.version < (3,5):
