(sorry, accidentally failed to send this to the list) All this extra syntax, whether it's ., #, or {} seems very heavy for a problem described as very rare. Why not simply use a declaration field name whose effect is to declare name :: r {name ::t} => r -> t name = getFld unless name is already in scope as a field name, in which case the declaration does nothing? Then we could continue to use standard functional notation for projection, and still deal with the case of unused projections. Barney.
