I'd love to hear an explanation of WHY this doesn't look like Python any more. For instance, is the + operator somehow wrong for Python, and it should have been the word "add"?
There's a very long tradition of using the symbol "+" to represent addition, so it's something most people are familiar with. There's no such tradition for the new operators being proposed.
Okay. What about bitwise operators, then? They don't have centuries of mathematical backing to support them, yet it isn't considered "unpythonic" to have &|^~ peppering our code.
They have decades of widespread presence in other programming languages, though.
Coalescing None to a value is _at least_ as common as performing bit manipulations in integers.
Certainly, but spelling that as a "?*" operator is a syntactical novelty. Consider that for the ternary operator, Python chose "B if A else C" over "A ? B : C", even though the latter had precedent in several languages. Regards Antoine.
