Yes, they should be made scope. The specs already say something similar.

> An implementation may construct the object or array instance on the stack. Therefore, it is an error to refer to that instance after the variadic function has returned

> But even if this will work, currently scope is not well implemented.

Yes, we're missing escape analysis but that's no argument for implicit heap
copies.
