:o

I fetched the sources (I tried to select the latest ones), and attached 
that DParser to my own code. I copied the set-ups from trunk/d1.0/dparser/
dmd/main.d, and do parsing and semantic passes 1 to 3 to build the parsed 
tree.

Problems:

- Parser segfaults, if it parses std.stdio

- I'm trying to write a tree walker; I have walk(X) functions for 
different types of elements (Module, FuncDeclaration, 
DeclStatement, ...). But I have hard times to determine the types of 
statements, since Statement class contains only a few "isXXXX()" 
functions. I tried to use typeid(typeof(s)), but it returns - as you may 
guess - always the type that was declared in the function arguments.

---
I use DMD1.030, and I have those 1.030 phobos sources.

I'll try to figure out how to extract that statement type information 
from parse tree, and could wait for newer versions of DParser.

At the same time I'll try to get dil compiled; although dil does not 
generate code, it might still be a suitable platform to write a software 
to generate some common warnings (just for my personal use, I'm not 
intended to start to write "dlint"). Unfortunately it means that I need 
to figure out how those DSSS & Tango things work :)
