* 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.
