 There is a data type `WrappedMonad` in `Control.Applicative`. It provides
 an `Applicative` instance for a type based on the `Monad` instance. This
 type hasn't been useful since AMP landed in GHC 7.10 about three years
 ago. I propose that this type be marked deprecated in GHC 8.6 and then
 removed in GHC 8.8.
