Support context manager protocol by contextvars.Token #129889
Description
Feature or enhancement
Proposal:
Sometimes, mostly in tests, I write something like
from contextvars import ContextVar
var = ContextVar('var')
def test_a():
token = var.set('new val')
do_stuff()
var.reset(token)It looks a little cumbersome, the support for with var: would be awesome:
def test_b():
with var.set('new val'):
do_stuff()
Has this already been discussed elsewhere?
