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. Judging by the current
levels of backlash against symbolic operators, it would have been
better to use "more explicit" function calls for all bitwise
operations. Coalescing None to a value is _at least_ as common as
performing bit manipulations in integers.
