+   File Name:          15.6.4.js
+   ECMA Section:       Properties of the Boolean Prototype Object
+   Description:
+   The Boolean prototype object is itself a Boolean object (its [[Class]] is "
+   Boolean") whose value is false.
+
+   The value of the internal [[Prototype]] property of the Boolean prototype
+   object is the Object prototype object (15.2.3.1).
+
+   In following descriptions of functions that are properties of the Boolean
+   prototype object, the phrase "this Boolean object" refers to the object that
+   is the this value for the invocation of the function; it is an error if
+   this does not refer to an object for which the value of the internal
+   [[Class]] property is "Boolean". Also, the phrase "this boolean value"
+   refers to the boolean value represented by this Boolean object, that is,
+   the value of the internal [[Value]] property of this Boolean object.
