FWIW I would be happy to help out with advice and direction, especially if the JVM backend could be rejiggered to take advantage of the new invokedynamic bytecode in Java 7. I have been using it for JRuby and have been very pleased with it.
Anyway, I really hope the JVM backend can move forward and I am standing by to help out as I am able. - Charlie (mobile) On May 11, 2011, at 16:56, Dario Bertini <berda...@gmail.com> wrote: > 2011/5/11 Michał Bendowski <mic...@bendowski.pl>: >> Welcome everyone :) >> >> I was wondering what is the current status of the JVM backend.
