 * Used for field references within the body of an around advice
 * to force the use of public access methods.  This makes it possible
 * for around advice to be inlined into any shadow to which it applies.
 * ??? this is very similar to PrivilegedFieldBinding and is somewhat related
 *     to InterTypeFieldBinding.  Maybe they have a common supertype?
