Wow, that's pretty impressive.  Does it do aliases also?

I read a little more last night and saw that there is an option 
for json output  from dmd, and tried it out.  Is that meant to 
serve the purpose of the gccxml program?


I also found mention of a c++ compiler that someone states can 
compile c++ and output C.  Kind of weird, but maybe compiling D 
to expanded D would not be such a stretch.
