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.
