HunPoS is a part of speech tagger in OCaml, implementing HMM with suffix recognition. This is a superb foundation for sequence HMM! Has a fast C lib. Didn’t build with my new OCaml 3.11 without ocamlfindlib.cmxa -- make world.opt didn’t do it, neither did make opt.opt.

Also found SWIG for OCaml, looking really mature with C++, representing class objects as closures. Am itching to wrap SRILM systematically in SWIG.
