 * A common use-case is returning a single value from an action. This provides a simple, type-safe superclass for such
 * results.
 * 
 * Note: Subclasses should provide both an empty constructor for serialization and a constructor with a single
 * value for normal use. It is recommended that the empty constructor is private or package-private.
