I think you'll find that most arduino projects are using a much more
capable avr chip, probably avr32 chips.
I wouldn't expect D will ever work well on 16bit microcontrollers, but on
32bit avr's I can't see any reason from my (limited) experience why the
toolchain wouldn't just build and work out of the box (at least under
You'll basically need to write the runtime yourself. If you avoid the GC
and OS stuff, you can basically stub out phobos, and you might be able to
run raw code quite easily...
