Jep, the concept for implementing Iterator and ArrayAccess is not that
trivial. I already thought about having an $storageIndex, but then you
also need an mapping of the index to the storage keys. And then the
question is, how to make shure you have an complete iterable object when
you unset elements with the ArrayAccess method.
