Artificial example (I have a different use case, but the pronciple is

interface ILinkedListItem {
LinkedListItem next();
void next(LinkedListItem v);

LinkedList objectStore;
class C : protected ILinkedListItem {
this()
{
objectStore.add(this);
}
protected LinkedListItem next() {...}
protected void next(LinkedListItem v) {...}
}
So the intent is that you don't have access to these methods from the
outside, but that C can still implement the interface to pass it only to
certain receivers (the objectStore list in this case).
Wouldn't making ILinkedListItem private do the same thing?

If it's in the same module, yes. But the more interesting case would be
if the interface is in its own module (in my case it's even a different
library).
