*Its just spelling*. If it is a useful and well-defined feature, we'll get used to the spelling soon enough.
That's not to say that spelling is not important *at all*, or that we should never prefer words to symbols. But if the only objection we have is "this is useful but I don't like the spelling so -1" then that's usually a pretty weak argument against the feature.
But we already have a spelling for the most common case. It is:
x = a if a is not None else b
That is the only use case of any of these operators that is actually common enough for me to care about --- but it's still not common enough to warrant the creation of a new operator, let alone multiple new operators.
That's a reasonable argument: "there's no need for this operator because...", albeit it is a subjective argument. (There's no objective rule about how common an operation should be before allowing it to be an operator.) What's not a reasonable argument is "I see that there could be a need for this operator, but I don't like the spelling so -1 on the entire proposal", which was my point. (One of my points.) -- Steve
