Is anyone working on a D source code formatting tool?

This conversation reminds me of something I've thought about ever 
since I first studied D. D takes the C preprocessor and folds it 
into the regular AST. But comments still seemed like the outlier. 
I looked through a bunch of source code and tried to figure out 
the most specific place anyone could possibly put a comment. The 
most detailed I found were something like:

enum X {
   ONE,
   TWO, // We need a TWO here
   THREE
}

So I started conceiving of a language in which even the 
*comments* were part of the AST. For, me this would be the 
aesthetic ideal. It just seemed like the next step in total AST 
integration.
