VSCode, TypeGuard, and TypeVar throw error

[dsm-72]

I am using python 3.11

$ python --version
Python 3.11.4

Here is the output that I get from VSCode Output tab, any ideas?

Name: ufmt
Module: ufmt

This was fixed in typing-extensions 4.6.0 (python/typing_extensions#243). It looks from your output like you're using a ufmt VSCode extension that bundles an old version of typing-extensions. That extension should upgrade its bundled packages; not sure whether it's controlled by this repository or something else.

@JelleZijlstra thank you for the info. So it seems that it is beyond my control for the moment.

[zsol]

It's controlled by https://github.com/omnilib/vscode-ufmt

The version of typing-extensions was changed in omnilib/vscode-ufmt@c1862df -- I suspect this should be fixed now.
