Comment (by bgamari):

 > The whole project of moving from the existing to the new TypeRep needs
 someone to lead it; maybe that can be your weekend project!

 Indeed I have been eyeing it. I thought exposing kind representations
 would be a good warm-up, although at various points over the weekend I've
 considered going all-in and going ahead with the new `TypeRep`.
