Do you plan to implement a version for the fastest benchmark 
"n-body" 
(http://benchmarksgame.alioth.debian.org/u64q/nbody.html) as well?

Adding D to the performance comparison of 
https://github.com/derekmolloy/exploringBB/tree/master/chp05/performance (companion code to the book "Exploring BeagleBone - Tools and Techniques For Building With Embedded Linux") could be good promotion in the embedded domain (where performance, Linux compatibility and code maintainability matters).
