Comment(by dreixel):

 You raise an interesting point, thanks. I think replacing `Rec1 f` with `f
 :.: Par1` would be possible. But I'm not too keen on making a change to
 the representation right now, as I think there might be more fundamental
 changes coming up anyway (e.g. making use of `DataKinds`). But I'm leaving
 this open so that we don't forget the idea.
