recently, as you might have noted by a previous post of mine, that
American Mathematical Society published a series of articles on formal
proofs in 2008 November. See: http://www.ams.org/notices/200811/ The

ok, i've been reading these Ocaml tutorials in the past few days:
intro to ocaml, from official site
