/** A type-specific {@link List}; provides some additional methods that use polymorphism to avoid (un)boxing.
*
* Note that this type-specific interface extends {@link Comparable}: it is expected that implementing
* classes perform a lexicographical comparison using the standard operator "less then" for primitive types,
* and the usual {@link Comparable#compareTo(Object) compareTo()} method for objects.
*
*
Additionally, this interface strengthens {@link #listIterator()},
* {@link #listIterator(int)} and {@link #subList(int,int)}.
*
*
Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous
* sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations
* of these methods, it is expected that concrete implementation override them with optimized versions.
