 /**

    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.
