The overall advice here (add comments to your code to delineate different 'sections" of a file) is ultimately a bad hack to deal with the fact that your codebase is not structured well into function / modules / classes with a single responsibility and the right level of composition. Refactor your codebase to put the related code together, and then this "problem" will disappear and your code will be much easier to change in the future
