For tail call and exception, the best is to keep exception and use "let 
try" contruct
(a camlp4 extension is available, but the coding is quite simple):

let try x =  expr  in
  normal_case
with
  e -> exc_case

is translated to

(try
   let x = expr in
   fun () -> normal_case
with
   e ->
     fun () -> exc_case) ()

This way you get tail call in norma_case and exc_case.

Hope this helps,
Christophe
