Thanks for the clarification and the answer link. I was also just debugging
along the similar lines around how OSError.__reduce__ treats the arguments
something like. Custom __reduce__ for aiohttp works as explained in the SO
answer.
class SubOSError(OSError):
def __init__(self, foo, os_error, /):
self.foo = foo
self.os_error = os_error
super().__init__(os_error.errno, os_error.strerror)
def __reduce__(self): # Custom __reduce__
return (self.__class__, (self.foo, self.os_error ))
def __reduce__(self): # OSError __reduce__
return (self.__class__, (self.os_error.errno, self.os_error.strerror ))
