In Fortran the comment is ! and how somebody wish to set headings is
really personal choice.

I use just one heading in Emacs Lisp:

;;;; ↝ MY EMACS LISP FUNCTIONS

And I like using Unicode that way.

;;;; ⧭⧭⧭⧭⧭⧭⧭⧭⧭ Or maybe like this

All that can work. Is it visual enough? That is what matters.

Or how about:

;⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞

;⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞⮞

I like those.

Headings and subheadings in outline mode don't exist in Fortran as a
language.  Outline Minor Mode is universal it is up to user to decide
what is heading and what not.

All of the above depends of settings, right?
