OK, I get what your aiming at here. Coming from a total AST approach,  
we have access to everything on a project scope if we set up the main  
program such as FlasconJS is setup.

I have actually written an ASDoc clone using falcon.

- check out the docs created by it using Velocity templates [0]

What this shows is I had full access to a compile session and was able  
to use the IDefinition API to traverse what I needed. Now we have the  
IASNode which will give us the method scopes and expressions.

Heh, the expressions are what I am afraid of but, you have done it! So  
I know it's possible and that is all I need for a flashlight.

I might make something in my whiteboard that starts on this idea  
within the next week and you can checking it out, we could then  
collaborate that way.

Not a problem, I won't confuse you right at the moment as it's still  
taking shape.

This is what I am counting on. Apache Flex is a GREEN project, we are  
recycling 100s of thousands of hours of developer and CPU time into a  
future. Thus Apache Flex is reducing the carbon foot print... heheh
