Please feedback for Zend bug #66331 ZEND_SEND_PREFER_REF issue trying to overlad

See https://bugs.php.net/bug.php?id=66331 With PHPUnit real use cse (trying to mock memcached class) We have more options in Extension land that in user land. Of course if will be great to be able to correctly handle those arginfo mapping in userland, but we have, for now, no way to say "PREFER_REF" in PHP land. So my proposal is to make proto check a little less stric and consider ZEND_SEND_PREFER_REF as ZEND_SEND_REF, so this will allow to override a internal class method (using "prefer") in a php class. Any better idea ? Or could I apply this fix ? Remi.
