> This is not a language that is optimizing for being written by humans

I've taken a look at the code - having never written a line of Guix in my life - and it seems very readable to me. It's cleanly structured and makes good use of indentation.

The string "))))))))))", which you claim you're seeing 'regularly', appears exactly twice in 4,580 lines of code. It's the longest parens string that appears in the file. Seems to me like you deliberately searched for the most atypical example, that you're now misrepresenting as 'regular', when it is highly atypical.

And honestly, what would that look like in some 'more normal' language?

              );
            }
          );
        ];
      };
    )()();

I will never understand this fear response some people have to seeing `(fn a b)` instead of `fn(a, b)`.
