? (setq rmail-mode-hook 'rmail:mode:hook)

? (defun rmail:mode:hook () ...)

One fact that may not be widely known about lisp is that a symbol
may have *both* a function *and* a variable binding. There is nothing
wrong with saying "(setq rmail-mode-hook 'rmail-mode-hook)" followed
by "(defun rmail-mode-hook () ...)". And it is even marginally more
efficient, as you save a symbol, at the possible expense of confusion.

In fact, once having done the above, you can now refer to rmail-mode-hook
without the quote, since it evals to itself! Ain't LISP wonderful?
