The all() will strip any duplicates, so if the number of elements in
all(@items) is the same as @items, then @items has no duplicates.
OK, but you are not using the 'set with additional behavior' of
junctions. How would that be spelled with a pure set?
set(@items).elements.size === @items.size
perhaps? This would nicely blend with the junction forms. Would
it even be the case that Set is a super role of the junctions?
