 * 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.
