* Verify that the engine doesn't change in construct_twice.phpt * Clean up the implementation of Randomizer::__construct() Instead of manually checking whether the constructor was already called, we rely on the `readonly` modifier of the `$engine` property. Additionally use `object_init_ex()` instead of manually calling `->create_object()`.
