Sometimes call time pass by reference is useful, for example when you want to make it possible to omit an param (normally passed by reference) by setting null. With no call time pass by reference, programmers are required to write:
$null = null; foo($null); Deleting it isn't a good idea, it should become a normal (not deprecated) language feature. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
