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)
