I have no idea, this is a prototype. It uses JBurg which is a bottom  
up rewritter so I guess anything could be emitted based on the  
semantics of the js language.

Probably but if you look at the code, there are serious issues.

That being said, I think Alex tried to warn that this was just a prototype.

Also, I would have no idea where to begin hacking this stuff since it  
uses the byte code emitter for SWF then visits nodes (I think) with  
the JSEmitter.

I'm guessing it compiles to virtual SWF byte code because the emitter  
has already taken care of ActionScript semantics.

For anything done with this code, there will have to be others that  
have a clue to whats going on. I don't know if what is there is the  
best way to implement a cross compiler. I would have to study this  
stuff more.

It will be interesting to hear others opinions eventually.
