PEP 563 postponed to Python 3.11

[frenzymadness]

Hello.

Deferred evaluation of type annotations has been postponed to Python 3.11: https://mail.python.org/archives/list/python-dev@python.org/thread/CLVXXPQ2T2LQ5MP2Y53VVQFCXYWQJHKZ/

Currently, I see only two test failures with the latest Python 3.10b1 (for the latest attrs release) and they are both already fixed in 03d3fc7 but there are more changes than that so I don't know whether the compatibility with Python 3.10 needs any more work or not.

Could you please add Python 3.10 to CI? It should be pretty stable in the beta phase.

What makes you think that 3.10 is not part of the CI? We've just had to pin 3.10 to alpha7 due to the beta1 & pytest breakage but it's been there for a while.

I'm sorry, I saw a commit message saying "Disable 3.10 until it stops breaking" and assumed that this part of the CI is disabled now. I should check it.

Do you think that the current master is compatible with the 3.10 beta?

[hynek]

Yes, I've re-enabled b1 while responding to you. To circle back to your original message: attrs was passing on 3.10 deferred evaluation; we just had to disable 3.10 for a while it due to breakage with (I think) typed-ast that wasn't our fault.

(also 21.1 is going out this week. i'm just tying up loose ends atm)

Closing this since I don’t think there is anything to do.
