This module exports the templates for automatic instance deriving of Rank2 type classes. The most common way to use it would be
import qualified Rank2.TH data MyDataType f = ... $(Rank2.TH.deriveAll ''MyDataType)
or, if you're picky, you can invoke only deriveFunctor
and whichever other instances you need instead.
