I tried to do this. But I don't quite understand the relation of
modify-syntax-entry and define-generic-mode. 

Does the meaning of the regexes (like in ;;1) depend on the 

Why do the regexes ;;a and ;;b match parts of the same "word" (where
word is any string that doesn't contain \s characters)? 

According to C-h f define-generic-modeI, ;;2 is a FUNCTION-LIST
argument. Why isn't it possible to write '((modify-syntax-entry ?/
"w")) at this place?


;; grammar-mode
(define-generic-mode 'grammar-mode
  '(                                                                  ;;1
    ("\\([\\*\\+\\?]\\)"          1 'font-lock-function-name-face)
    ("\\([:]\\)"                  1 'font-lock-warning-face)
    ("\\(/[^\\s]+\\)"             1 'font-lock-string-face)           ;;a
    ("\\([A-Z][A-Za-z0-9]*\\)"    1 'font-lock-type-face)             ;;b
  nil                                                                 ;;2
