Comment (by hvr):

 Replying to [comment:9 hvr]:
 > have to avoid using `AutoDeriveTypeable` at the same time with
 `NoImplicitPrelude`, as otherwise you get the error

 Nevermind that, as all modules in `base` obviously have to have
 `NoImplicitPrelude` on. There's something else causing that error, as
 `Data.Monoid` and `Control.Applicative` work fine having
 `AutoDeriveTypeable` and `NoImplicitPrelude` enabled at the same time.
