The PEP text specifies::
Values within an enumeration cannot be meaningfully compared
except with values from the same enumeration. The comparison
operation functions return ``NotImplemented`` when a value from an
enumeration is compared against any value not from the same
enumeration or of a different type
The Python parser knows what to do when a comparison returns
NotImplemented.
