[Chiara Modenese <c.modenese@xxxxxxxxx>]

Ok! Thanks all for suggestions. I agree that for now it is simpler to code
it in the Law functor. I will do and then test it with before commit. I let
you know if issues arise. Anyway, I will probably not be able to commit it
before Christmas -- in case someone else needed it (btw, Happy Christmas to
everyone!).

Cheers, Chiara
