* Date: 28 August 2001
*
* SUMMARY: A [DontEnum] prop, if overridden, should appear in for-in loops.
* See http://bugzilla.mozilla.org/show_bug.cgi?id=90596
*
* NOTE: some inefficiencies in the test are made for the sake of readability.
* For example, we quote string values like "Hi" in lines like this:
*
*                    actual = enumerateThis(obj);
*                    expect = '{prop:"Hi"}';
*
* But enumerateThis(obj) gets literal value Hi for obj.prop, not
* literal "Hi".  We take care of all these details in the
* compactThis(), sortThis() functions.  Sorting properties
* alphabetically is necessary for the test to work in Rhino.
