Proposal for Stage 0 of a contextual 'super()' operation in ES7

equivalence.js

class Parent extends Person {
  constructor() {
    super(arg1, arg2);
    
    // desugars to
    // InitializeThis(<activefunction>.__proto__.[[Construct]]([arg1, arg2], NewTarget);
  }
  
  someMethod() {
    // these are equivalent
    super(arg1, arg2);
    super.someMethod(arg1, arg2);
  }
  
  get someProperty() {
    // these are equivalent
    super();
    super.someProperty;
  }
  
  set someProperty(val) {
    // these are equivalent
    super(val);
    super.someProperty = val;
  }
}

spec-detail.js

// [[HomeObject]] is Parent
class Parent extends Person {
  constructor() {
    super(arg1, arg2);
    
    // desugars to
    // InitializeThis(<activefunction>.__proto__.[[Construct]]([arg1, arg2], NewTarget);
  }
  
  someMethod() {
    super(arg1, arg2);
    // desugars to
    // [[HomeObject]].[[Prototype]].[[Get]]("someMethod", this).[[Call]](this, arg1, arg2);
    
    super.someMethod(arg1, arg2);
    // desugars to (the same thing)
    // [[HomeObject]].[[Prototype]].[[Get]]("someMethod", this).[[Call]](this, arg1, arg2);
  }
  
  get someProperty() {
    super();
    // desugars to
    // [[HomeObject]].[[Prototype]].[[Get]]("someProperty", this)
    
    super.someProperty;
    // desugars to (the same thing)
    // [[HomeObject]].[[Prototype]].[[Get]]("someProperty", this)
  }
  
  set someProperty(val) {
    super(val);
    // desugars to
    // [[HomeObject]].[[Prototype]].[[Get]]("someProperty", this)
    
    super.someProperty = val;
    // desugars to (the same thing)
    // [[HomeObject]].[[Prototype]].[[Set]]("someProperty", val, this)
  }
