More explicitly, the goal isn't to implement a different language than D.

Simply doing the parsing/AST building in a way that would allow AST 
macro to be introduced later.

Your 3 points seem reasonable. Mine were :
  * Implement something that can parse D as it is currently 
defined/implemented (if dmd's behavior and spec differs, it is handled 
on a per case basis).
  * Discard all deprecated features. Not even try to implement them even 
if dmd support them currently.
  * Do the parsing in several steps to allow different tools to work 
with it.

I think we both have very compatibles goals. Let me do a clean package 
of it I write about design goals. I don't have that much time right now 
to do it, I will this week end.
