+   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).
