This is fairly easy to do. You can simply call:
Loop.compile("...")
instead of Loop.run() and this will return a class file representing the script. You can also call Loop.implement() to get a loop-backed Java interface that you pass in.
Finally, you can inspect the raw bytecode by setting a system property:
java -jar loop.jar myscript.loop -Dprint_bytecode=true
Is there something else you were after?
