+* 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.
