If think that the end goal of a project like this, putting a D frontend 
in Phobos, should be that the compiler should be built using this 
library. This would result in the compiler and library always being in 
sync and having the same behavior. Otherwise it's easy this would be 
just another tool that tries to lex and parse D code, always being out 
of sync with the compiler and not having the same behavior.

For this to happen, for Walter to start using this, I think there would 
be a greater change if the frontend was a port of the DMD frontend and 
not changed too much.
