C# calls the ?? operator the "null-coalescing" operator. I have
absolutely no idea why, but that does give precedence for calling
it "coalesce". Then again, who wants to memorize how that's
spelled? They also have "GetValueOrDefault()" on Nullable<>, but
that is kinda long. How about just "orDefault" or "ifNull"?
