The behaviour of the d9 iterators appear to me very unspecific. In which 
order does it iterate through the elements? What happens if I delete an 
element while iterating, maybe even the current. Does an iterator stay 
valid if I remove the element from the container? How can I change how 
the iterator behaves? etc.
