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