Wow, you converted DMC++'s front-end to D?

To chime in on that, Calypso i.e the LDC+Clang equivalent of what 
you described isn't dead (it just revived a few weeks ago from a 
long slumber) and it should be possible to make a smaller 
codegen-less version for DMD that only depends on a few Clang and 
LLVM support libraries. Another possibility..
