Yeah, I've been planning to try and get this into D one day.
Probably
something like:
(a ?: b) -> (auto __tmp = a, __tmp ? __tmp : b)
gcc used to have that extension and they dropped it...
But GCC can't control the C++ language spec. Naturally there is a
reluctance to add nonstandard features. It's a successful feature
in C#, however, and a lot of people (including me) have also been
pestering the C# crew for "null dot" (for safely calling methods
on object references that might be null.)
I don't see why you would use ?: instead of ??, though.
