The "funcall" in there is expected to scan through (point)...end and move point accordingly, so once you call `scheme-syntax-propertize-regexp-1` you're already "too far". Instead you need to turn (syntax-propertize-rules ("\\(#\\);" (1 (prog1 "< cn" (scheme-syntax-propertize-sexp-comment (point) end))))) into something like: (syntax-propertize-rules ("\\(#\\);" (1 (prog1 "< cn" (scheme-syntax-propertize-sexp-comment (point) end)))) ("\\(#\\)/" (1 (prog1 "|" (scheme-syntax-propertize-sexp-comment (point) end)))) and then extend `scheme-syntax-propertize-sexp-comment` so it handles the case when point is inside a regexp (based on `syntax-ppss`, just like it currently does for the case where point is inside a sexp-comment). [ And probably rename it while you're at it since it will not be only for "sexp comment" any more. ] Stefan
