I don't think we should be adding future stubs to asciimatics... Have you offered them to the future package maintainer instead?

Looks like they might be amenable.... PythonCharmers/python-future#490

Hm, didn't think about that. That could be a solution, yes. I also agree that having the stubs in our repo wouldn't be very nice.

Indeed haha. Time to solve a 1 and a half year old issue. Ok, so I'll send them a PR and, in the meanwhile, solve other things with this one.

Would you recommend me to send PIL a similar PR? Since Mypy complained about stubs for it as well. They also have an open issue for that: python-pillow/Pillow#2625.

[peterbrittain]

Yeah - it looks like they also ground to a halt. Might be worth pointing out that type stubs can now be used in the package according to https://www.python.org/dev/peps/pep-0561/
