ECMA Section: 15.2.1.1 The Object Constructor Called as a Function:
Object(value)
Description: When Object is called as a function rather than as a
constructor, the following steps are taken:
1. If value is null or undefined, create and return a
new object with no properties other than internal
properties exactly as if the object constructor
had been called on that same value (15.2.2.1).
2. Return ToObject (value), whose rules are:
undefined generate a runtime error
null generate a runtime error
boolean create a new Boolean object whose default
value is the value of the boolean.
number Create a new Number object whose default
value is the value of the number.
string Create a new String object whose default
value is the value of the string.
object Return the input argument (no conversion).
