Your timings are good enough for me, I have updated the 
rosettacode page with the third D version.

In the second D program if you compile with ldc2 the final switch 
gives a significant performance increase :-)

This was discussed some time ago. Probably there are ways for 
ldc2 to use a little better the static information of well 
annotated D code.
