In python 3.6 you can use name "async" for variable: >>> class A: ... async = True ... >>> but in python 3.7a4 you catch syntax error: >>> class A: ... async = True File "", line 2 async = True ^ SyntaxError: invalid syntax >>>

See https://docs.python.org/3.7/whatsnew/3.5.html#new-keywords.

Yes, I understand, but "not recommended" != "not allowed". For example library Pika (https://pypi.python.org/pypi/pika) use variable "async", so no one project that use lib Pika can't be launched on Python 3.7a4

It raised a DeprecationWarning since 3.5. Most projects got rid of "async" and "await" identifiers before 3.7. File a bug in the Pika library.
