I see same error at ArchLinux python 9 and Centos7 python 3.6

asyncari installed by pip or by cloning this repo (same result).

Yeah, there's some old not-anyio3-compatible code in there that needs to be modernized.

Pull Request welcome, otherwise I'll get to it sometime sooner or later.

[Regela]

I added pull-reguest, I am waiting for comments

[Regela]

Hello. Can we continue this task?

[smurfix]

Merged and pushed. Thank you, and sorry for the delay, $DAY_JOB takes up a lot of time at the moment.
