michael@0:  * SUMMARY:  Testing scope with nested functions
michael@0:  *
michael@0:  * From correspondence with Christopher Oliver <coliver@mminternet.com>:
michael@0:  *
michael@0:  * > Running this test with Rhino produces the following exception:
michael@0:  * >
michael@0:  * > uncaught JavaScript exception: undefined: Cannot find default value for
michael@0:  * > object. (line 3)
michael@0:  * >
michael@0:  * > This is due to a bug in org.mozilla.javascript.NativeCall which doesn't
michael@0:  * > implement toString or valueOf or override getDefaultValue.
michael@0:  * > However, even after I hacked in an implementation of getDefaultValue in
michael@0:  * > NativeCall, Rhino still produces a different result then SpiderMonkey:
michael@0:  * >
michael@0:  * > [object Call]
michael@0:  * > [object Object]
michael@0:  * > [object Call]
michael@0:  *
michael@0:  * Note the results should be:
michael@0:  *
michael@0:  *   [object global]
michael@0:  *   [object Object]
michael@0:  *   [object global]
michael@0:  *
michael@0:  * This is what we are checking for in this testcase -
