I was trying to make emacs load up a file of TeX functions only the
first time tex-mode or latex-mode came up, using the latex-mode-hook
and the tex-mode-hook variables.  The code below (in my .emacs) didn't
work (tex-stuff was never loaded, and the local-set-key didn't work):

(defvar latex-nifties-loaded nil)
(defun kim-latex-mode-hook ()
  (if (not latex-nifties-loaded)
      (progn (load "tex-stuff")
	     (setq latex-nifties-loaded t)))
  (local-set-key "\C-c\C-i" 'LaTeX-insert-begin-end))
(setq latex-mode-hook 'kim-latex-mode-hook)
(setq tex-mode-hook 'kim-latex-mode-hook)

Only when I replaced the defun'd function with a straight lambda
function did the hooks run:

(setq latex-mode-hook '(lambda ()
			 (if (not latex-nifties-loaded)
			     (progn (load "tex-stuff")
				    (setq latex-nifties-loaded t)))
			 (local-set-key "\C-c\C-i" 'LaTeX-insert-begin-end)))

Any ideas?  Thanks!
