Feature or enhancement

Proposal:

Sometimes, mostly in tests, I write something like

fromcontextvarsimportContextVarvar=ContextVar('var')deftest_a():token=var.set('new val')do_stuff()var.reset(token)

It looks a little cumbersome, the support forwith var: would be awesome:

def test_b():    with var.set('new val'):        do_stuff()

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
