    • No instance for (Eq (Process a))

        (maybe you haven't applied a function to enough arguments?)
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Eq (Continuation a))
