Wesley said that function objects have a "heaping distinction" of
being callable. Only he can say for sure what that means; I took it to
mean that being callable is a very special property, perhaps one that
only function objects have. I just wanted to point out that there is
nothing really very special about that property, any more than being
iterable or having a length or a string representation or any of the
other properties that are implemented with special methods.

Not that I can think of off-hand though maybe there is some pathological case...

Yes, my point is that it is very easy to create such an object.
