You're taking the contrived, cut-down example too literally :-).  The
numbers were easier to type to test this out,  I was using symbols in
fact, :x, :y, and :z  in the first place, but the problem is more
general than that because a case statement can be used with anything
that copes with ===.

        Thanks anyway :-),
