+ *
+ * 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 -
