Nice numbers. I’m not a Python guy but I was under the impression 
that Numpy actually is written in C, so that when you benchmark 
Numpy you’re mostly benchmarking C, not Python. Therefore I had 
expected the Numpy performance to be much closer to D’s. An 
important factor I think, which I’m not sure you have discussed 
(didn’t look too closely), is the compiler backend that was used 
to compile D and Numpy. Then again, as a user one is mostly 
interested in the out-of-the-box performance, which this seems to 
be a good measure of.
