Yeah, I noticed that right after sending the email, sorry.

So I tried to use a macro even if happens to have the same name as the
keyword, since that form is a bit more flexible, but it is fine either
way.

What I would suggest is adding to the comment that these were decided
to be used as keywords, and thus we only need to define them as empty
in the disabled case.

Thanks!

Cheers,
