Quick notes:

  • A few of these are fixable in typeshed. For example, I already changed bytes.__add__ recently to reflect that bytes() + bytearray() works at runtime. Looks like binascii.hexlify needs similar changes.
  • We'll probably need to change the overlapping equality check to continue to special case bytearray and memoryview.

anyio one is an incorrect annotation, fixed in https://github.com/agronholm/anyio/pull/434

As you can see, we have already done some cleanup thanks to this work :wink:

Waiting for python/typeshed#9082 to clean things completely.

Thanks @dvarrazzo, this is great!

Looks like the discord one is fixed by python/typeshed#9036, and the pyspark one by python/typeshed#8995.

For the QImage error: PySide6 is fairly quick to resolve type issues (less than a week everytime I openned or commented on one). I haven't fully followed the whole bytes promotion and Buffer Protocol lately, so I don't know if I'm the best to propose changes. But as a C-extension python binding I think they'll want to use the newly exposed Buffer Protocol.

Edit: Opened issue on Qt/PySide6's Jira: https://bugreports.qt.io/browse/PYSIDE-2476
