async and await will be keywords in Python 3.7

[JelleZijlstra]

I'm planning to keep the old names around, but add aliases for compatibility. Existing code should continue to work.

Both the suggestions sound good to me. Thanks for raising this!
Will try to get to this sometime soon, but feel free to also submit pull requests.

sgtm.

might be a good time to evaluate if we want to keep this decorator with parenthesis since the asyncio one is without and it'd trip people.

Since this sounds like a breaking change, what's the proposed migration path?
Since 3.7 won't come out until 2018-06-15 (see https://www.python.org/dev/peps/pep-0537/), maybe this is better postponed?
