Lower than C?

You have have read this already, but I have found it interesting:

They show me why D may enjoy gaining some things at a level even lower than C, to allow it to use the modern CPUs better.
There one comment by spc476 reminds me that D can actually have vector ops too someday ;-)
I think it may exist a language that is both safe enough and allows to give hints to the compiler with a nice syntax to allow some of the optimizations that article discusses a lot about.
