 * SUMMARY:  Testing scope with nested functions
 *
 * From correspondence with Christopher Oliver <coliver@mminternet.com>:
 *
 * > Running this test with Rhino produces the following exception:
 * >
 * > uncaught JavaScript exception: undefined: Cannot find default value for
 * > object. (line 3)
 * >
 * > This is due to a bug in org.mozilla.javascript.NativeCall which doesn't
 * > implement toString or valueOf or override getDefaultValue.
 * > However, even after I hacked in an implementation of getDefaultValue in
 * > NativeCall, Rhino still produces a different result then SpiderMonkey:
 * >
 * > [object Call]
 * > [object Object]
 * > [object Call]
 *
 * Note the results should be:
 *
 *   [object global]
 *   [object Object]
 *   [object global]
 *
 * This is what we are checking for in this testcase -
