Giampaolo Rodola' added the comment:
ExitStack() already covers the "null ctx mgr" use case described in the first
message. Original example:
with transaction or contextlib.null():
...
By using ExitStack:
with transaction or ExitStack():
...
You can push this further and do this, which is even more flexible:
with ExitStack() as stack:
if condition:
stack.enter_context(transaction)
...
So ExitStack really is better than the original proposal which could have made
sense 6 years ago but not anymore.
