 * An element that describes a type modifier as described in the
 * JVMS.
 *  
 * This allows for a more expressive and type safe alternative of defining a type's or type member's modifiers.
 * However, note that modifier's that apply competing modifiers (such as {@code private} and {@code protected}
 * should not be combined and will result in invalid types. An exception is thrown when built-in modifiers that
 * cannot be combined are used together.
