  // objects inherit the default valueOf method of the Object object;
  // that simply returns the itself. Since the default valueOf() method
  // does not return a primitive value, ES next tries to convert the object
  // to a number by calling its toString() method and converting the
  // resulting string to a number.
  //
  // The toString( ) method on Array converts the array elements to strings,
  // then returns the result of concatenating these strings, with commas in
  // between. An array with no elements converts to the empty string, which
  // converts to the number 0. If an array has a single element that is a
  // number n, the array converts to a string representation of n, which is
  // then converted back to n itself. If an array contains more than one element,
  // or if its one element is not a number, the array converts to NaN.
 var i = Array.prototype.indexOf.call({length: [ ]}, 1);
