9 ECMA Section: 15.2.2.1 The Object Constructor: new Object( value )
10
11 1.If the type of the value is not Object, go to step 4.
12 2.If the value is a native ECMAScript object, do not create a new object; simply return value.
13 3.If the value is a host object, then actions are taken and a result is returned in an
14 implementation-dependent manner that may depend on the host object.
15 4.If the type of the value is String, return ToObject(value).
16 5.If the type of the value is Boolean, return ToObject(value).
17 6.If the type of the value is Number, return ToObject(value).
18 7.(The type of the value must be Null or Undefined.) Create a new native ECMAScript object.
19 The [[Prototype]] property of the newly constructed object is set to the Object prototype object.
20 The [[Class]] property of the newly constructed object is set to "Object".
21 The newly constructed object has no [[Value]] property.
22 Return the newly created native object.
23
24 Description: This does not test cases where the object is a host object.
