python 3.10 AttributeError

[pepebc]

Everything was fine but with the python update to 3.10 this happens:

loop = asyncio.get_event_loop()
Traceback (most recent call last):
; File "/usr/lib/python3.10/site-packages/pysnmp/carrier/asyncio/dgram/base.py", line 93, in openClientMode
self._lport = getattr(asyncio, 'async')(c)
;AttributeError: module 'asyncio' has no attribute 'async'

I had a similar experience. The package is used with Home Assistant and the error I got was
