This is just to let you know that you can now try Mezzo online! Mezzo runs in your browser, thanks to js_of_ocaml and a few hacks to glue the type-checker to the web interface. There’s a few examples, and you can type-check and/or interpret your programs (currently, only the graph traversal actually does something observable).

There’s a lot of room for improvement (currently, all files are loaded during initialization, for instance), but it believe it’s nice enough already that I can release it. It is known to work in the latest versions of Firefox, Chrome and Internet Explorer.
