ArrayObject does not have a `current` method[1] (it does not implement Iterator, but rather IteratorAggregate), so it is never called, and therefore the `parent::current()` call doesn't error, from what I can tell. For what it's worth, overriding the `offsetGet` method works as expected[2]. [1] <https://3v4l.org/0o55V> [2] <https://3v4l.org/1njNa> -- Christoph M.
