File Name: 15.5.4.2-3.js
ECMA Section: 15.5.4.2 String.prototype.toString()
Description: Returns this string value. Note that, for a String
object, the toString() method happens to return the same
thing as the valueOf() method.
The toString function is not generic; it generates a
runtime error if its this value is not a String object.
Therefore it connot be transferred to the other kinds of
objects for use as a method.
