It still needs a lot of work though; some compilers missing parts, platforms not supported. That said, it's not an effort to address D's natural vector syntax, the key goal is to provide a hardware SIMD API that is as orthogonal as possible and portable (with confidence it will run reasonably well). I wonder if druntime could be enhanced to use the SIMD stuff though in the functions that perform the natural vector operations, might offer some nice little boosts.
