As of base 4.7.0.1, none of the newtype wrappers in Data.Monoid have instances for: - Typeable - Data - Functor It looks like the base library repository has AutoDeriveTypeable, so I presume that takes care of the Typeable instances. It also looks like First and Last now have Functor instances, amongst others. In particular, I would like to add Functor instances for all parameterized types, where applicable (i.e. Dual, Sum, Product). In general, I think we should add whatever other instances make sense. Data came to mind. Others? Discussion period: 2 weeks (or perhaps until after the beginning of the new year) Regards, Sean
