DeprecationWarning: "@coroutine" decorator is deprecated

[ylassoued]

Module mock.py, function proxy, declared in line 599, uses decorator @asyncio.coroutine.
It seems that the asyncio @coroutine decorator is deprecated since Python 3.8.
Please use async def instead.
Source code should be modified to look something like:

           async def proxy():
            try:
                if inspect.isawaitable(result):
                    return (yield from result)
                else:
                    return result
            finally:
                _mock_self.await_count += 1
                _mock_self.await_args = _call
                _mock_self.await_args_list.append(_call)
                yield from _mock_self.awaited._notify()

Asynctest partially works on 3.8 but fails almost completely on 3.9, see #132 and #144. So it's much bigger than just the use of @coroutine.

Thanks @RemiCardona! Hmmm, this is really disappointing! Does this mean that I should just avoid using this API for Python 3.8 and above? Or is a new version, with full support for Python 3.8+, planned?

In my case python 3.11 complains:
