newtype GenericProduct a

Product type with generic instances of Semigroup and Monoid.

This is similar to Generically in most cases, but GenericProduct also works for types T with deriving via GenericProduct U, where U is a generic product type coercible to, but distinct from T. In particular, U may not have an instance of Semigroup, which Generically requires.

Example

>>> :set -XDeriveGeneric -XDerivingVia
>>> data Point a = Point a a deriving Generic
>>> :{
  newtype Vector a = Vector (Point a)
    deriving (Semigroup, Monoid)
      via GenericProduct (Point (Sum a))
:}

If it were via Generically (Point (Sum a)) instead, then Vector's mappend (the Monoid method) would be defined as Point's (<>) (the Semigroup method), which might not exist, or might not be equivalent to Vector's generic Semigroup instance, which would be unlawful.
