Just to drive this point home.

Manually implemented stride and fill with everything forced 
inline. Otherwise, the original code is unchanged.

17 ms, 891 μs, and 6 hnsecs
15 ms, 694 μs, and 1 hnsec
15 ms, 570 μs, and 9 hnsecs

My new stride outperformed std.range stride, and the manual 
for-loop. And, because the third test uses the new stride, it 
also benefited. But interestingly runs every so slightly faster...
