Description

On Python 3.12.3 onwards (specifically 3.12.3), a change to EnumType.__call__ messed up our own overriding of the same function at DistinctFlag.__call__, causing issues like those seen in #1657. This PR fixes that with version-specific code.

Changes

• Make DistinctFlag.__call__ use a separate branch of code for 3.12.3+.
  • This code is forced to recreate the entirety of EnumType.__call__ due to a singleton that is not exported. This adds quite a burden to us, but hopefully it should be alright.
  • Versions before 3.12.3 should still use the same code as previously.
