  24     ECMA Section:       15.2.1.1  The Object Constructor Called as a Function:
  25                                   Object(value)
  26     Description:        When Object is called as a function rather than as a
  27                         constructor, the following steps are taken:
  28
  29                         1.  If value is null or undefined, create and return a
  30                             new object with no properties other than internal
  31                             properties exactly as if the object constructor
  32                             had been called on that same value (15.2.2.1).
  33                         2.  Return ToObject (value), whose rules are:
  34
  35                         undefined   generate a runtime error
  36                         null        generate a runtime error
  37                         boolean     create a new Boolean object whose default
  38                                     value is the value of the boolean.
  39                         number      Create a new Number object whose default
  40                                     value is the value of the number.
  41                         string      Create a new String object whose default
  42                                     value is the value of the string.
  43                         object      Return the input argument (no conversion).
