As someone who uses both D and Python every day, I find that - 
once you are proficient in both - initial productivity is higher 
in Python and then D starts to overtake as a project gets larger 
and/or has stricter requirements. I hope never to have to write 
anything longer than a thousand lines in Python ever again.
