Add W606 warning for async and await keywords in Python 3.7 - #684
Merged
Conversation
From https://docs.python.org/3/whatsnew/3.6.html#new-keywords > async and await are not recommended to be used as variable, class, > function or module names. Introduced by PEP 492 in Python 3.5, they > will become proper keywords in Python 3.7. Starting in Python 3.6, the > use of async or await as names will generate a DeprecationWarning. By adding a warning to pycodestyle.py these future warnings and syntax errors can be caught during static code analysis. The await expression tests were taken from PEP-492. https://www.python.org/dev/peps/pep-0492/#id58
