Right, but see my second message --- I'm only interested in canonicity
up to structural equality and I'm happy with O(N) comparison. So it's
just the "no matter what order you add things you get the same tree"
property that I care about. But it's not yet obvious to me whether I
can even achieve that much.
John.
