Hey,=20
  I was unable to write faster OCaml implementation. ;)

  I was supposed to write C++ raytracer for studies. Just to learn how
to write raytracers I've written at first a version in OCaml (code +
desc. here: http://bla.thera.be/archives/17).
It took < 900 lines of
code to make it working while C++ version had 4000 lines when it started
rendering anything interesting (code here:
http://repo.or.cz/w/blaRAY.git,
some doc., no pictures:
http://temp.thera.be/blaRAY/refman.html.d/).

  But still C++ was faster. ;s This programs are too big to serve as
benchmarks, but someone might be interested.=20
