Kevin Shweh <[email protected]> added the comment:
It seems like the straightforward, minimal fix would be to just add
if (getattr(cls, '_is_protocol', False) and
not getattr(cls, '_is_runtime_protocol', False) and
not _allow_reckless_class_cheks()):
raise TypeError(...)
to _ProtocolMeta.__instancecheck__. Does that fail on some edge case (that the
current implementation works on)? It's a little weird that
_ProtocolMeta.__instancecheck__ doesn't explicitly check that the protocol is
runtime-checkable.
