This would, of course, be more idiomatic as

(when-let ((match (rx-string-match "[a-z]" string)))
  (foo)
  (bar (match match 0)))

Another thing that occurred to me is that we could allow the match
object accessors to return nil on nil objects.  Then, what's currently
this:

(let ((string (foo)))
  (and (string-match "[a-z]" string)
       (match-string 0 string)))

would just be this:

(match (rx-string-match "[a-z]" (foo)) 0)
