Can't make it a single underscore? Question mark works best

It *could* be an underscore; the only thing is that the
underscore is a valid variable name, so the above expression
would actually be binding two variables, which might surprise
someone who was expecting otherwise. I don't really care all
that much, but it's something to think about.
Why not just leave an empty space, like php does:
$info = array('coffee', 'brown', 'caffeine');
// let's skip to only the third one
list( , , $power) = $info;
echo "I need $power!\n";
