42 ECMA Section: 15.5.2 The String Constructor
43 15.5.2.1 new String(value)
46 Description: When String is called as part of a new expression, it
47 is a constructor; it initializes the newly constructed
50 - The prototype property of the newly constructed
51 object is set to the original String prototype object,
52 the one that is the intial value of String.prototype
53 - The internal [[Class]] property of the object is "String"
54 - The value of the object is ToString(value).
55 - If no value is specified, its value is the empty string.
