* 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 -
