If you pay me I can produce a faster D version of whatever small 
program you want.
But the reality is that noone really _needs_ those benchmark 
programs, and thinking about optimizing them is an adequate 
punishment for writing them.

The only things I can think of where C++ could wins a bit against 
D was that the ICC compiler could auto-vectorize transcendentals. 
Like logf in a loop, which LLVM doesn't do.
But the ICC compiler has been moving to LLVM recently.

When your compiler see the same IR from different front-end 
language, in the end it is the same codegen.
