    File Name:          15.2.1.2.js
    ECMA Section:       15.2.1.2  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 proerties 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).
