fix(python): Allows parens around `with` context exprs #521

Closed kopecs closed 2 years ago

kopecs commented 2 years ago

This PR adds support for parentheses around with context expressions. Previously, we allowed code like:

with open(x) as a, open(y) as b:
    pass

but not

with (open(x) as a, open(y) as b):
    pass

(or with a trailing comma)

After this PR, both would parse correctly.
