[Python-Dev] Accepting PEP 492 (async/await)

[Guido van Rossum]

I totally forgot to publicly congratulate Yury on this PEP. He's put a huge
effort into writing the PEP and the implementation and managing the
discussion, first on python-ideas, later on python-dev. Congrats, Yury! And
thanks for your efforts. Godspeed.
