[1 of 5] Compiling Control.Monad.CC.Prompt ( Control/Monad/CC/Prompt.hs, dist/build/Control/Monad/CC/Prompt.o )

Control/Monad/CC/Prompt.hs:52:24: error:
    • No instance for (Applicative (P ans m))
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Monad (P ans m))
