That's likely not an option for PHP itself, but having the _option_ of a vec > equivalent (in this proposal "list") would make sense, I think. 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?
