Polishing D - suggestions and comments

[Robert Fraser]

You mentioned IDEs a couple times, specifically in that they should be 
able to access DMD via some sort of API. While this would be great, 
Descent (in trunk, sadly the kinks are still being worked out...) takes 
a different approach. We have a full Java port of the DMD semantic 
front-end, which we are using to do things like display errors inline as 
the user types. From working with Descent, I can say that having 
programatic access to the AST would be nice, but since most advanced 
IDEs would want to extend it anyway, it's a lot of work for a small gain.
