This struct is a wrapper around the allocator and size data members of a list. It takes advantage of the empty-base optimization (EBO) so that if the allocator is stateless, it takes up no space.

: public allocator_traits<ALLOCATOR>::rebind_traits<List_Node<VALUE>>::allocator_typeTBD: This struct should eventually be replaced by the use of a general EBO-enabled component that provides a pair-like interface. (A properly-optimized tuple would do the job.)
