I still like the approach of doing  `import typing as t` -  (or other short name of ones preference). 

Bcause in the end, any argument used to bring "Any" as a built-in could be used in favor
of any other element in typing anway.

Typing "t.Any, t.Union, t.Optional" is not a hassle and immediately readable, even by someone
who just opened the file and skipped the "import" session. No need for tens of names
from "typing.*" to be on the module namespace (or builtins).

But you got the gist.

In the future, it's really better to use plain text for email lists.

Did you forget to paste the text? Or did gmail eat it?

That's probably a question for the Pylance devs, but my guess is that
anything flagged as "Any" type is the same as flagging it as "I don't
know what that type is".

Yes, Python 3.10 makes the `from __future__ import annotations`
behaviour occur automatically. See PEP 563:

https://www.python.org/dev/peps/pep-0563/

(At least, I'm guessing that's what is happening here, it has to be a
guess because I can't see the code you run and the error you get.)
