Each major mode should have a mode hook named modename-mode-hook. The
major mode command should run that hook, with run-hooks, as the very

The order in the source file shouldn't matter because when Emacs
(add-hook 'LaTeX-mode-hook 'brad-setup-LaTeX-keybindings)
add-hook will store the symbol in the hook but doesn't need to access
the symbol's function definition. That the symbol has a function cell
(i.e., there actually exists a function named
brad-setup-LaTeX-keybindings) is only relevant when the hook is
executed. By that time, obviously, the called function must have been

have .emacs.el (require 'brad-foobar)...
