Marcus, could you plz look at it?

Fixed most of the issue in head but not like you expected to.

If you clone an ArrayIterator you also clone its reference thus the described behavior below is correct.

If you clone an ArrayObject you clone the array, too. However the behavior is not completely correct yet.
