That is something you can't quite escape in Nix either. While it doesn't use parenthesis like a Lisp, the nature of the language and the depths of the sets you are dealing with still makes you end up getting a lot of this at the end of your files:

        ];
      };
    };
  };
}

Having one } too many or too few is a pretty common issue with Nix and feels very similar to Lisp, even when the rest of the language is quite different.
