Working on it now.

make some good improvements to the current spec that will help
with the MIC work.

Jakob at least seems interested in the for loop stuff.  Am I reading you

Frankly, the way things are with the x86 SIMD stuff is not scalable.
I'd like to clean some of that up, in an incremental way, of course.
