Instead of doing it this way, why not make a font-lock matcher that
looks at *every* initial sexp atom, calls intern-soft on it, and applies
a face that depends on properties of the found symbol? This way, we'd
update fontification not only after load, but also after eval-defun, and
it'd be easy to make a `declare'-form that provided for exceptions from
the general rule.
cc-mode uses a system like this for keywords, and I think it's what
Stefan was talking about earlier.
