With MetaOCaml you can -- see either the long version
http://www.cas.mcmaster.ca/~carette/scp_metamonads.pdf
or the more condensed version

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
