Is a Python property a callable attribute?
>>> class Lorem:
... @property
... def spam(self):
... print(self)
...
>>> foo = Lorem()
>>> foo.spam()
<__main__.Lorem object at 0x7ff5078bc710>
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is not callable
It seems that no, a property is not a callable attribute.
So I remain dumbfounded as to why anyone would want a class to *both* be
an enumerated type, *and* have callable attributes in its API.
