 All that needed to be said. You're absolutely right.

 To me, the by-ref sounds like a better solution. It will also allow
 someone to do $found === true, $found === false, $found === null to
 determine whether the key was found, it wasn't found, or it hasn't been
 implemented for the object cache yet, the last one additionally causing a
 notice. It's elegant, if you ask me.
