Then we don't really need the re-match function at all...
(let-re-match (overall (beg end)) ("regexp")
...)
or
(let-re-match "regexp" (overall (beg end))
...)
(or something) would be sufficient...
But I think this would be too somewhat cumbersome. Like, if you want to
write
(while (setq m1 (re-search "foo"))
(setq m2 (re-match "[0-9]"))
(zot (re-string m1 0) (re-end m2 0)))
you quickly find yourself deeply nested, and sometimes with awkward ways
of using the let-ret-matched variable if you want to use it later,
outside the form, etc.
Hm...
