[issue42725] PEP 563: Should the behavior change for yield/yield from's

[Guido van Rossum]

Guido van Rossum <gvanrossum at gmail.com> added the comment:

I don’t really care how you do it, I just thought having a whole “expr-without-walrus-or-yield” subgrammar would be tedious.

If there is a way to have the “in-an-annotation” flag set during parsing that may be better, I don’t know.

Maybe Lysandros has an idea?
