The "__eq__ compares identity" was a glib pseudo-implementation; I
didn't think it through. The existing 'enum' implementation doesn't
use identity, and future ones won't either.
The intended meaning was more like:
def __eq__(self, other):
result = compare_attribute_values(self, other)
In other words, identity doesn't matter, but every value from every
enumeration will compare inequal to each other. If an EnumValue
instance is copied, the copies will compare equal.
