Ah, OK thanks.  I'd noticed no existing unit tests had had duplicate
numbers/objects in the 'items' list.... and an implementation I was
considering, I realized relied on that... :)

... BTW also I'm noticing the objects in the unit tests are all
Enumerable.  Can we depend on the objects in the arrays being
"sortable", or just testable for equality?


Thanks,
