+    File Name:          15.4.1.2.js
+    ECMA Section:       15.4.1.2 Array(len)
+
+    Description:        When Array is called as a function rather than as a
+                        constructor, it creates and initializes a new array
+                        object.  Thus, the function call Array(...) is
+                        equivalent to the object creationi new Array(...) with
+                        the same arguments.
+
+                        An array is created and returned as if by the
+                        expression new Array(len).
