42 ECMA Section: 15 Native ECMAScript Objects
43 Description: Every built-in prototype object has the Object prototype
44 object, which is the value of the expression
45 Object.prototype (15.2.3.1) as the value of its internal
46 [[Prototype]] property, except the Object prototype
49 Every native object associated with a program-created
50 function also has the Object prototype object as the
51 value of its internal [[Prototype]] property.
