Hi andreas

this is clear. I really understand. This is why we asked mathieu to  
work on that and propose this project as SummerTalk project.
This would be great to have real exception too not subclass of String  
like in the default compiler for syntax error. :)
Mathieu already fixed a lot of things in the new compiler related to  
pragmas parsing. Now he is focusing
on the error handling and may be after he will work on the decompiler  
If people wants to help we need the decompiler also working well.
Mathieu also worked on fixing the way comments are attached in the  
tree (before this was kind of random).
