"an object used for or capable of holding, esp for transport or storage,
such as a carton, box, etc."
Linked list is a data structure which may serve as an implementation of a
container. But the list itself is nether an object, nor is capable to
transport or store anything, just common sense. As always, reference
manuals are free to disagree with it.

Yes, that is why forcing referential semantics is bad.

That is why I don't care about iterators as they spoil interface with
identity.

I don't need to, some people consider pointers harmful, some enjoy them.
That is out of the scope of this discussions. Assuming that pointers are
bad, so are the iterators.
