/**
   File Name:          boolean-001.js
   Description:        Corresponds to ecma/Boolean/15.6.4.3-4-n.js

   15.6.4.3 Boolean.prototype.valueOf()
   Returns this boolean value.

   The valueOf function is not generic; it generates
   a runtime error if its this value is not a Boolean
   object.  Therefore it cannot be transferred to other
   kinds of objects for use as a method.
