Description:

This is an OrderedCollection with weak references to its element.
Elements may vanish and are silently replaced by nil, if the
referred to element looses its last non-weak reference.
The logical size of the instance or the element slots are not
affected - thus, when an element is lost.
So be prepared to get nil when accessing/enumerating.
