Deprecation warning for async and await

[Marco Buttu]

I enabled the deprecation warning in Python 3.5.1 and Python 3.6 dev, 
but I did not get any warning when assigning to async or await:

$ python -Wd -c "import sys; print(sys.version); async = 33"
3.5.1 (default, Jan 21 2016, 19:59:28)
[GCC 4.8.4]

Is it normal?
