Correction of above for the op_and is here:

Is there some way to encapsulate op_and, or_or, false_ and true_ in
some sort of typeclass for a boolean lattice:

?

It seems if I had used such a typeclass, it would be more likely
that I would have avoided the above copy&paste error by
forcing me to be more careful.
