Sorry to be a pedant, but this is not correct. The optimisation is only
possible when the arguments
are unsigned integers which I don't think is specifiable when working in OCAM

Hi,
I'm happy to announce the first official release of Js_of_ocaml,
a compiler from OCaml bytecode to Javascript.
This tool let you write OCaml programs that run on Web browsers.
Js_of_ocaml is easy to install, and use thereafter, as it works with
an existing installation of OCaml, with no need

Jerome,
Thank you, this sounds fantastic!
One small question: could you expand on your last comment:

Do you mean all tail-calls come a large cost, or on
