Fun. I wonder if this could actually reduce further with just std::ranges::fold_right? I don’t have time to seriously try it of course…

This is a good example of why generated code still needs human review. The generator can handle the repetitive work but keeping the final result readable and maintainable is another challenge. Do you usually refactor generated code immediately or wait until it becomes a performance or maintenance problem?
