src/MoresmauJP/Util/Random.hs:14:24: error:
    • No instance for (Applicative (RandT 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 (RandT m))
