Hasn't happened yet... I see this PEP as written in a bit of haste and
very close to the 3.6b1 feature freeze (coming weekend). Usually I
wouldn't accept such a hasty PEP, but the ideas in it seem pretty
uncontroversial, and in line with the existing expectations for
async/await.

Yury, if you manage to get a working implementation signed off by one
other core dev (not me) I can accept the PEP provisionally, under the
same conditions as PEP 525.
