yeah you are right, passing arguments by reference doesn't trigger the notice, but I'm not sure that it is applicable in our case.
Yeah, it wouldn't help. For instance, 42 or "default" can't be passed by reference, so you couldn't actually provide a default value to coalesce() if you implemented it like that, which would make it pretty useless. :-) Ben. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
