    Interface INamespace

    Enumerating the nodes a namespace holds.

    The iterators walk the namespace's own index, so they yield only nodes belonging to this namespace, in insertion order, and they do not follow references into any other. A count is a plain size lookup rather than a walk, so preferring it to [...iterator()].length is worth doing on a large model.

    None of these iterators tolerate the namespace being modified while one is open, for the same reason a Map iterator does not: adding or removing a node invalidates it. Collect into an array first when the loop body adds nodes.
