As a D novice still struggling with the concept that composable 
range-based functions can be more efficient than good-old looping 
(ya, I know, cache friendliness and GC avoidance), I find it 
extremely interesting that someone as expert as yourself would 
reach for a C-like approach for serious data crunching. Given 
that data crunching is the kind of thing I need to do a lot, I'm 
wondering how general your statement above might be at this time 
w.r.t. this and possibly other domains.
