[Carter Cheng]

Thanks Doug. I apologize if this is slightly off-topic- but my
motivation in this case is to try to understand the context of the
clang C++ parser design (if you knew where to find some of the
relevant materials for this I would appreciate it- though perhaps you
could send this to me directly if this place is inappropriate).
