Well, my first question would be why are you using named anything in an
enumeration, where it's going to get another name?
But setting that aside, if you
--> print(NEI.x.__name__)
'x'
not 'the-x'.
Now let's look for the clues:
class Enum...
...
@StealthProperty
def name(self):
return self._name
class NamedInt...
...
def __name__(self):
return self._name # look familiar?
When NamedInt goes looking for _name, it finds the one on `x`, not the one on
`x.value`.
