Small C programs compile a *lot* faster than small D programs that use
Phobos.

yikes, even doing printf in D is slow nowadays

Larger D programs do better, of course, at least if you compile all the
files at once (and don't use so much CTFE that it starts thrashing the
swap file).
Those are implementation issues, right?
