This seems pretty easy to achieve, although it's a bit messy. Seems like
you might be able to clean it up with camlp4. Here's the basic idea:
exception Return
let f ... =
let rval = ref None in
try
....
rval := Some ...;
raise Return
....
with
Return ->
match rval with
None -> "Bug! function ended without returning"
| Some x -> x
