i'm not sure what's wrong.

Here's my code:

(defvar xlsl-keywords-regexp (regexp-opt xlsl-keywords 'word))
(defvar xlsl-type-regexp (regexp-opt xlsl-types 'words))
(defvar xlsl-constant-regexp (regexp-opt xlsl-constants 'words))
(defvar xlsl-event-regexp (regexp-opt xlsl-events 'words))
(defvar xlsl-functions-regexp (regexp-opt xlsl-functions 'words))

(setq xlsl-font-lock-keywords
  `(
    (,xlsl-type-regexp . font-lock-type-face)
    (,xlsl-constant-regexp . font-lock-constant-face)
    (,xlsl-event-regexp . font-lock-builtin-face)
    (,xlsl-functions-regexp . font-lock-function-name-face)
    (,xlsl-keywords-regexp . font-lock-keyword-face)
))

but still, when i type for example “information”, the “for” is
highlighted.

Any other idea?
