    1.10 + * Date: 28 August 2001
    1.11 + *
    1.12 + * SUMMARY: A [DontEnum] prop, if overridden, should appear in for-in loops.
    1.13 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=90596
    1.14 + *
    1.15 + * NOTE: some inefficiencies in the test are made for the sake of readability.
    1.16 + * For example, we quote string values like "Hi" in lines like this:
    1.17 + *
    1.18 + *                    actual = enumerateThis(obj);
    1.19 + *                    expect = '{prop:"Hi"}';
    1.20 + *
    1.21 + * But enumerateThis(obj) gets literal value Hi for obj.prop, not
    1.22 + * literal "Hi".  We take care of all these details in the
    1.23 + * compactThis(), sortThis() functions.  Sorting properties
    1.24 + * alphabetically is necessary for the test to work in Rhino.
