+/**
+   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.
