	There is also Cgm.Data.Functor.Sum in cognimeta-utils, though it 
doesn't come with a Functor instance for some reason. I think I prefer 
Data.Functor.Sum to Data.Functor.Coproduct. There may be more 
occurrences in Hackage, hiding under less obious names.

	I presume this addition to Transformers would require a new proposal?
