Ways to parse D code.

[Jan Hönig]

What is the "easiest" way to parse D code?

Given an Expression/Statement/Function/Template.... I want to put 
it into a program, and it returns me an AST.

D-Scanner seems to do that with `--ast` argument. I would need to 
dig into it, to get it programmatically, instead of as XML on the 
stdout.

libdparse seems to do it as well with `parseModule` function.

dmd has to do it somewhere as well. Although I don't know exactly 
where. I do know ldc uses dmd's frontend for parsing.

I am also a little confused about who uses what. Does D-Scanner 
use libdparse?
Is there a D grammar for pegged?

Thank you for any hints!
