[Python-ideas] PEP 505: None-aware operators: operators ?= and ?? and OR

[Nathan]

Hello.

Even if I'm -1 on the general idea of a None-aware, for a lot of reason already mentionned in this thread, the syntax "??" proposed (that I find much less readable than the current version) is still better IMHO.
How many programmer will read "||" or "OR" as a classic "or" operator? Programmers needs to learn the language, but making it easy for them to understand and learn is important in python.
More than that, if you use "||" or "OR" thinking you use "or", nothing will help you to understand what isn't working in your code.
So -1 on that idea even if PEP 505 were accepted.

I would think `||` would be much better.
It could be a kind of "semantic or" which could use the aforementioned dunder has_value.
-1, though, but to the general None-awareness.
