+ *  Description:
+ *
+ * http://scopus.mcom.com/bugsplat/show_bug.cgi?id=324455
+ *
+ *  Earlier versions of JavaScript supported access to the arguments property
+ *  of the function object. This property held the arguments to the function.
+ *  function f() {
+ *      return f.arguments[0];    // deprecated
+ *  }
+ *  var x = f(3);    // x will be 3
+ *
+ * This feature is not a part of the final ECMA standard. Instead, scripts
+ * should simply use just "arguments":
+ *
+ * function f() {
+ *    return arguments[0];    // okay
+ * }
+ *
+ * var x = f(3);    // x will be 3
+ *
+ * Again, this feature was motivated by performance concerns. Access to the
+ * arguments property is not threadsafe, which is of particular concern in
+ * server environments. Also, the compiler can generate better code for
+ * functions because it can tell when the arguments are being accessed only by
+ * name and avoid setting up the arguments object.

+ * - the actual result
+ *
+ * For example, a test might look like this:
+ *
+ * var zip = /[\d]{5}$/;
+ *
+ * AddTestCase(
+ * "zip = /[\d]{5}$/; \"PO Box 12345 Boston, MA 02134\".match(zip)",   // description of the test
