There is also the issue with equals/hashCode. You can test the equality of two lists using List.equals(), you can test the equality of two sets using Set.equals(), but you can not compare two SequencedCollection using equals. A SequencedCollection basically occupy the same lattice as Collection and do not provide enough guarantee to be different than Collection. Rémi
