+   File Name:          15.4.5.2-2.js
+   ECMA Section:       Array.length
+   Description:
+   15.4.5.2 length
+   The length property of this Array object is always numerically greater
+   than the name of every property whose name is an array index.
+
+   The length property has the attributes { DontEnum, DontDelete }.
+
+   This test verifies that the Array.length property is not Read Only.
