https://github.com/python/cpython/commit/4142961b9f5ad3bf93976a6a7162f8049e354018
New submission from Serhiy Storchaka :
This warning was introduced in 3.6. The reason is that in most other regular

flag
Serhiy Storchaka added the comment:
This warning was introduced in 3.6. It is a time to convert it into an error.
RE error messages contain position.
But I understand that very few users will use 3.11 in nearest future, so I am
going to add a position to warning message and backport

Serhiy Storchaka added the comment:
Yes, it is the same. I should search before writing a patch.
But for some reasons I prefer my solution over the one proposed in issue42766:
The code is clearer and more strict, tests use public API instead of a private
method

Serhiy Storchaka added the comment:
Also Future.result() and Future.exception() can raise a CancelledError. So a
CancelledError raised in a task may not contain a message passed to
Task.cancel().
import asyncio
import random
async def main():
fut = asyncio.Future()
fut.cancel
Serhiy Storchaka added the comment:
For reference, the msg parameter of Task.cancel() was added in issue31033.
It seems that the initial use case was for debugging. I do not see how it
differs from the following example:
r = random.random()
if r < 0.5:
x = 0
e

async_lru_cache() and async_cached_property() can be written using that
decorator. The implementation of async_lru_cache() is complicated because the
interface of lru_cache() is complicated. But it is simpler than using
_lru_cache_wrapper().

Serhiy Storchaka added the comment:
I think that it would be simpler to add a decorator which wraps the result of
an asynchronous function into an object which can be awaited more than once:
def reawaitable(func):
@wraps(func)
def wrapper(*args, **kwargs):
return
