Trying to run the tests with typing_extensions>=4.12 (released 3 weeks ago) results in about 10 errors with message mashumaro.exceptions.UnserializableDataError: typing_extensions.NoDefault as a field type is not supported by mashumaro. With typing_extensions==4.11 the tests are collected without errors.
The relevant changelog entry is:
Backport the typing.NoDefault sentinel object from Python 3.13. TypeVars, ParamSpecs and TypeVarTuples without default values now have their default attribute set to this sentinel value.
