I feel I should mention, in case any Emacs users missed it, that the
Emacs Erlang mode recently took a small step in this direction. It is
now possible to have different colours for the function name in a
function definition depending on whether the function is exported or not
(though the default settings use the same colour for both cases). Set
erlang-font-lock-exported-function-name-face to suit your taste.
