Syntax for calling “super” in Java 8 Defender methods

This is a very interesting discussion. How to reference default methods from implemented interfaces throughout the class / interface hierarchy? Situation:


interface K {
  int m() default { return 88; }
}

interface J extends K {
  int m() default { return K.super.m(); }
                        // ^^^^^^^^^^^^ How to express this?
}

Solution ideas:

K.super.m()
super.K.m()
((K) super).m()
K::m()
K.default.m()
super<K>.m()
super(K).m()
super(K.class).m()
super[K].m()

Any other crazy ideas? See the discussion here: http://mail.openjdk.java.net/pipermail/lambda-dev/2012-August/005616.html
