That's a horrible syntax, but a fantastic name for a language construct to do the job. Even
better might be (something like) first_isset($a, $b, $c) which tells you precisely what's
happening: you get the first value that passes the isset() test.
I also find the ?? / ??= suggestion very attractive - it would have been my suggestion for a
suitable operator.
Cheers!
