Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, haskell/actions/setup@v2, actions/cache@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

As of 2023-09-09, haskell/action/setup is no longer maintained, please switch to haskell-actions/setup (note: dash for slash).

The import of ‘Control.Applicative’ is redundant
