D compiler front end in Phobos (was: syntax definition language)

[Gor Gyolchanyan]

cool!
I really _REALY_ want to get a working D front-end into Phobos.
preferably during my lifetime.
Obviously there's some work already done in this area.
I'd like us to chip in and discuss this in-depth and come up with a
plan to do this.
AFAIK everyone was in favor of a front-end as a library solution.
