    // %        note 1: not reliable anyways
    // %        note 2: Note also that IE retains information about property position even
    // %        note 2: after being supposedly deleted, so use of this function may produce
    // %        note 2: unexpected results in IE if you later attempt to add back properties
    // %        note 2: with the same keys that had been deleted
    // -    depends on: is_int
    // *     example 1: input = {4: "red", 'abc': "green", 2: "blue", 'dud': "yellow"};
