Control/Monad/Atom.hs:52:23: error:
    • No instance for (Applicative (AtomT a 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 (AtomT a m))
