	Both at the same time because many of them call construct() in call() and I'm not keen on adding a bunch of temporary plumbing to turn exceptions into throw completions. Also changes the return value of construct() to Object* instead of Value as it always needs to return an object; allowing an arbitrary Value is a massive foot gun.
