+   File Name:          15.5.4.2-2-n.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.
