Sure.  Think of it as:

  (defun run-hook (h)
    (let ((inhibit nil)
          (funs (symbol-value h)))
      (while funs
        (let ((fun (pop funs)))
           ((eq 'not (car-safe fun)) (push fun inhibit))
           ((member fun inhibit) nil)
           ((eq t fun) (setq funs (append (default-value h) funs)))
           (t (funcall fun)))))))
