note 40148 deleted from language.references.return by curt

Note Submitter: contact@infopol.fr ---- I've noticed that if you systematically use function & functionName () {}; The calls with or without & will work as intended (that is the caller can decide if he/she wants a reference or a copy). Kind of strange programming, I think (setting the reference or value return from the calling script) but I think if PHPeople really wanted to endorse it, they'd put & automatically before each function call.
