As of April 2004, the OCaml support in SWIG http://www.swig.org was only
being used by the author of said support.
http://mailman.cs.uchicago.edu/pipermail/swig/2004-April/009508.html
I have not followed up on it since then, but I keep almost finding a
reason to do so. My interest is tied to the issue of Ocaml-ifying the
Nebula2 3D engine, http://nebuladevice.cubik.org . It is a C++ engine
so this is a big job.
