3.12.2 python problem with Functor subclass check

[banderlog]

Hi, the next error appears on python3.12.2:

 File "/venv/lib/python3.12/site-packages/oslash/_init_.py", line 11, in <module>
    from .state import State
  File "/venv/lib/python3.12/site-packages/oslash/state.py", line 78, in <module>
    assert issubclass(State, Functor)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.12/typing.py", line 1841, in _subclasscheck_
    cls._non_callable_proto_members_
AttributeError: type object 'Functor' has no attribute '_non_callable_proto_members_'

with 3.11 everything is fine

oslash-0.6.3 (latest)
