Maybe just because of habit, but I think the main downside of `rx` is
that it's very verbose, which ends up hiding the "text". For example in
(rx "(def" (or "macro" "un" "subst")))
I find the `or` to get a bit in the way of my visual cortex recognizing
the "defmacro" pattern above.

Yes, it's the downside.
