With MetaOCaml you can -- see either the long version
or the more condensed version

With a little bit of work, you can achieve all of

automatically.  There are three drawbacks:
1) the code you write no longer looks like O'Caml but Lisp instead [can 
be fixed with enough campl4 hacking]
2) the error messages can be very difficult to figure out [could be 
improved a lot if monads were integrated in O'Caml]
3) metaocaml is not as well supported as ocaml
