[issue39702] PEP 614: Relaxing Grammar Restrictions On Decorators

[Brandt Bucher]

New submission from Brandt Bucher <brandtbucher at gmail.com>:

The attached PR implements PEP 614's revised grammar for decorators, with tests. In short:

decorator: '@' dotted_name [ '(' [arglist] ')' ] NEWLINE

becomes

decorator: '@' namedexpr_test NEWLINE

I'm marking it as DO-NOT-MERGE until the PEP is accepted, but code review is still appreciated. Discussion of the PEP itself should go to the Python-Dev thread:
