The more verbose syntax is actually a == null ? b : a
or equivalently a != null ? a : b
. Personally I don't see an obvious expansion of a ?: b
to either of those.
One other syntax to consider would be a else b
. But ??
is more similar to ?.

If you look around, this same operator is spelled either ??
or ?:
in a bunch of different languages. I don't think either one has a big majority. C# and Swift use ??
, PHP and Groovy use ?:
.
Personally, I prefer ??
, in particular because it ties in nicely with Sean's suggestion about compound assignment in #6.
