     24     ECMA Section:       15.5.4.3 String.prototype.valueOf()
     25 
     26     Description:        Returns this string value.
     27 
     28                         The valueOf function is not generic; it generates a
     29                         runtime error if its this value is not a String object.
     30                         Therefore it connot be transferred to the other kinds of
     31                         objects for use as a method.
