    6. If iterable is either undefined or null, let iter be undefined.
    7. Else,
      a. Let adder be Get(set, "add").
      b. ReturnIfAbrupt(adder).

Object.defineProperty(Set.prototype, 'add', {
  get: function() {
    throw new MyError();
  }
});

new Set();

assert.throws(MyError, function() {
