That's a big enough change that it should be in What's New as well (at
least in the porting section, and probably more prominent than that).
The current lack of DeprecationWarnings in 3.6 is a fairly major
oversight/bug, though:
Python 3.6.2 (default, Oct 2 2017, 16:51:32)
[GCC 7.2.1 20170915 (Red Hat 7.2.1-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> await = 1
>>> async = 1
>>> print(async, await)
1 1
So if we're going to go ahead with making them real keywords in 3.7
(as specified in PEP 492), then the missing DeprecationWarning problem
in 3.6 needs to be fixed.
Cheers,
Nick.
