+/**
+   File Name:          15.4-2.js
+   ECMA Section:       15.4 Array Objects
+
+   Description:        Whenever a property is added whose name is an array
+   index, the length property is changed, if necessary,
+   to be one more than the numeric value of that array
+   index; and whenever the length property is changed,
+   every property whose name is an array index whose value
+   is not smaller  than the new length is automatically
+   deleted.  This constraint applies only to the Array
+   object itself, and is unaffected by length or array
+   index properties that may be inherited from its
+   prototype.
