  To save anyone the trouble, this project is totally empty yet.

  It doesn't say anything about the ability of the owner to port F# to the JVM, but just know that it is just a readme, three almost empty java classes, and the beginning of an ANTLR parser.

  So to answer other questions here, you can't even compare it to F# on Mono. F# on Mono works perfectly. The F# compiler and runtime is huge, and getting to parity will probably take at least a year to a very dedicated team.

  Very pleased to see this. F# is a really exciting language, hamstrung by being tied to the MS platform. Hoping we'll see more opensource F# projects as a result.

  Since F# was derived from OCaml, I think readers may also be interested in taking a look at the OCaml-Java project: http://ocamljava.x9c.fr/

  (It's essentially what it says in the tin...)

  Has anyone tried running the F# through IKVM[1] (.Net <-> java)? That wouldn't solve this, but it should be possible to run F# on a JavaVM.

  How is this supposed to work given the JVM does not support tail calls?

  How does mono's F# coverage compare to this?

  There is a good technical thread started on stackoverflow http://stackoverflow.com/questions/15731724/whats-the-easies...

  F# <- Ocaml <- ML language

  Have a look at Yeti ? http://mth.github.com/yeti/
