Hi!
In my opinion, it would make more sense, as was already suggested before, to require the return to be passed by reference only if the prototype specifies it should be passed by reference. This could be argued to be a form of return contravariance.
Yes, this makes sense. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
