Yep, though it seems a shame the accessors have to be slowed down just
so printing and equality can write back.

It's probably worth thinking about reduction policy.  Certainly
printing and equality need a reduced form, but if one never actually
does those then it might be nice to have some other way, either
automatic like under gc or explicit.
