Yes, that tool has two properties:
1) It works now. Not Soon(tm). You can download it, compile it, 
and use it to dump the AST of your D code in just a minute or two.
2) It wasn't built THE ONE TRUE WAY.

But we should take a step back first. Before we try to implement 
a parser for D's grammar, we need to figure out what exactly D's 
grammar is.

Seriously. We don't have a real grammar for D. We have the 
language spec on dlang.org, but it isn't complete, consistent, or 
updated when the language changes. Want examples? I have a 
tracker for them here: 
http://d.puremagic.com/issues/show_bug.cgi?id=10233

There's also my project here: 
https://github.com/Hackerpilot/DGrammar, but it's not official 
and I keep finding differences between it and the behavior of DMD.

Why am I the only one who thinks this is a problem?
