24 ECMA Section: 15.5.4.2 String.prototype.toString()
26 Description: Returns this string value. Note that, for a String
27 object, the toString() method happens to return the same
28 thing as the valueOf() method.
30 The toString function is not generic; it generates a
31 runtime error if its this value is not a String object.
32 Therefore it connot be transferred to the other kinds of
33 objects for use as a method.
