michael@0:  * SUMMARY: A [DontEnum] prop, if overridden, should appear in for-in loops.
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=90596
michael@0:  *
michael@0:  * NOTE: some inefficiencies in the test are made for the sake of readability.
michael@0:  * For example, we quote string values like "Hi" in lines like this:
michael@0:  *
michael@0:  *                    actual = enumerateThis(obj);
michael@0:  *                    expect = '{prop:"Hi"}';
michael@0:  *
michael@0:  * But enumerateThis(obj) gets literal value Hi for obj.prop, not
michael@0:  * literal "Hi".  We take care of all these details in the
michael@0:  * compactThis(), sortThis() functions.  Sorting properties
michael@0:  * alphabetically is necessary for the test to work in Rhino.
