Also sounds good to me, and even simpler implementation-wise. So I'm
happy to implement it that way if nobody comes up with a reason why
that's not the right way.
And we need to decide if we're opt-in, e.g.,
(defmacro foo ()
(declare font-lock-keyword) ...)
makes foo highlighted as a keyword, or if we're opt-out, e.g., all
macros are highlighted by default unless declared as
(defmacro foo ()
(declare no-font-lock-keyword) ...)
And I'm open to a better declaration names than the ones above.
Bye,
