Yeah, I already figured that value semantics would be preferred for this. From the engine perspective, we probably wouldn't want to special case these 3 types and would probably want to figure out some way for at least internal classes to have value semantics. Any contrarian opinions there, especially from main php-src contributors like Nikita and Dmitry? -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
