It's not something you can "introduce" in your regexp, it only makes sense within the context of a regexp built with rx: https://www.gnu.org/software/emacs/manual/html_node/elisp/Rx-Notation.html Rewriting your regexp as an rx regexp would not be too difficult if you want to go that route, Jean's example is a good template. Otherwise, as an approximation of that feature, you could built your regex string using the value of the variable comment-start ( ";" in emacs-lisp-mode) instead of hardcoding ;; . To be clear, the variable comment-start happens to have the same name as the symbol in (syntax comment-start), but they are not the same thing, the syntax classification can in theory be a lot smarter than simply regexp matching.
