These two pairs are behaviourally distinct, as shown by their .perl
outputs, but they get the same .WHICH strings. Presumably as a result,
=== claims them to be equivalent, though cmp correctly shows them to
be different. This is all very similar to [perl #128943] concerning
the Set class. Also, like Set.WHICH, Pair.WHICH on these pairs returns
plain strings as Str objects, rather than ObjAt objects.
