Incompatibility with pyright 1.1.394 #2856
Description
I use pyright --verifytypes on a project which depends on click. I do not use --ignoreexternal.
With pyright==1.1.394 I started seeing errors.
These are related to how pyright considers instance variables without explicit types to be ambiguous. See https://github.com/microsoft/pyright/blob/main/docs/typed-libraries.md#ambiguous-types.

This also shows up in Click's CI when requirements/typing.txt is updated to the latest pyright.
