ImportError: cannot import name 'CoroWrapper' from 'asyncio.coroutines' in Python 3.11

[seratch]

Hi there! I am a maintainer of the Python Slack SDKs, which support Falcon as one of third party web frameworks to run Slack apps. While running our tests with Python 3.11 (see https://github.com/slackapi/bolt-python/pull/751 for more details if necessary), I found that falcon/asgi/response.py raises ImportError with the latest major version. Here is the details of the error:

_______ ERROR collecting tests/adapter_tests_async/test_async_falcon.py ________
ImportError while importing test module '/home/runner/work/bolt-python/bolt-python/tests/adapter_tests_async/test_async_falcon.py'.
Hint: make sure your test modules/packages have valid Python names.

I believe that above stacktrace should be helpful enough for you but let me know if you need more information on it.

Hi @seratch! This is already fixed in master, but not released yet... We ought to cut 4.0 ASAP but we're a bit stretched on resources atm.

@vytas7 Thanks for your prompt reply! Also, it's great to know that the issue is already fixed in the latest revision. Look forward to checking if v4 works for us when it's out 👋
