I think a better quote would be "If i want *HARDWARE* vector
operations..."; this is not automatically faster by nature, it requires
strict self-control in terms of application, and very careful attention if
you want your code to be portable.

At the moment, yes.

I have a fork; some people are using it already. 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.
