There's no oversight. We had PendingDeprecationWarning for async/await names in 3.5, and DeprecationWarning in 3.6. You just need to enable warnings to see them: ~ ยป python3 -Wall Python 3.6.2 (default, Aug 2 2017, 22:29:27) [GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> async = 1 <stdin>:1: DeprecationWarning: 'async' and 'await' will become reserved keywords in Python 3.7 > 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. They are already keywords in 3.7, I've committed that change a month ago.
