Ok, I understand. I'm trying to stay away from the phrase of "my way".  
I just see it as an alternative that I understand. Which means I can  
actually develop it.

Word, that is exactly what it does. Not to mention it will also  
generate valid AS3 code from the AST as well. I'm actually writing it  
against AS3 code generation first because it is the way I see getting  
to most precise and comprehensive tests. Once it generates AS3 and is  
tested, we override what we need for JS emitters and test that  

I mean, I can build a framework in AS (like Alex's, or maybe

Yes, that is correct. I am doing no black majic here. We are just  
setting the foundation and rules for the language translations. Like I  
said, having the compiler be able to spit out compilable AS3 code  
first means the JS translation and how solid the compiler will be  
increases a bunch in my opinion.

I know, maybe others would just jump straight to JS output but, not  
me. I have to much experience to know that a thorough foundation will  
allow us to hit lightspeed down the road. Besides, I have the time  
right now to do this right IMHO.
