I'd add to this list a philosophy decision: D tries to make the correct 
way the easiest way and path of least resistance. A highly disciplined 
and skilled C coder could accomplish the effect, but practically 
speaking, this can help eliminate a class of errors due to programmer 
laziness or lack of understanding.
