super re-binding?

gistfile1.js

class P {
	foo() { console.log( "P 'foo'" ); }
}

class C extends P {
	foo() {
		super();
	}
}

var c1 = new C();
c1.foo(); // "P 'foo'"

var D = {
	foo: function() { console.log( "D 'foo'" ); }
};

var E = {
	foo: C.prototype.foo.toMethod( E, "foo" )
};

// Link E to D for delegation
Object.setPrototypeOf( E, D );

E.foo(); // D 'foo'

toMethod(..) takes a new [[HomeObject]] as first parameter, and optionally a new name for the method. super is derived as [[HomeObject]].[[Prototype]].
