Yes, I thought of that and came to the same conclusion. It's my understanding that None may not be an actual object, but a special memory location. I'm not sure though and didn't look it up.
Python does not have memory locations. None *is* an actual object. It has attributes, it has standard behaviours, it fits in the same object model as everything else in Python does.
As you said, "?" is not an operator, so "a?.b" clearly can't break down into "a? .b".
The problem is that '.' IS a stand-alone operator, so it's natural to visually parse `<expr>.b` as `<expr> .b`, but adding '?.' causes double takes, more mental load, general interruption of the flow of reading. It also sets up the later discussion of other possible uses of the '?' symbol that may or may not have more merit.
This is utter nonsense on par with trying to claim that "x <= y" should be parsed as if it's a modified form of assignment since "x = y" would be assignment. Do I really need to explain how two-character operators work? ChrisA
