1. using a template for a container like linked list is preferred to using
interfaces.
2. you can achieve something similar using inner classes or class literals:
class C
{
private class LLItem : ILinkedListItem{
LinkedListItem next() {...}
void next(LinkedListItem v) {...}
}
this()
{
objectStore.add(new LLItem);
}
}
