Hi,

in some of the published presentations about Nashorn, Attila (on behalf 
of the Nashourn team, I guess) speaks about his vision for a dynamic 
languages toolkit to be used by language implementers targeting the JVM. 
One of its main components is a new IR resembling untyped JVM bytecode.

I would be interested in hearing something more specific about this topic.

What is the current state-of-the-art?
What can be expected in the next few months?
Is there a discussion group somewhere?

Greetings
Raffaello
