I've been looking into OCaml a bit, and it looks interesting. Here are two articles, one on either side of the debate (sorry haven't figured out embedded links):
Stevey on OCaml (pros) - http://steve.yegge.googlepages.com/ocaml
Steingold on Ocaml (cons) - http://www.podval.org/~sds/ocaml-sucks.html
Anyone here an OCaml hacker?
