I don't actually know assembly language so no, this is all purely
empirical.

Hello Gareth,
I managed to get some free time to look at this and it would appear
that static foreach is slower than hand unrolling a loop. Fortunately
there are no detectable differences between hand unrolling a loop and
building the body of the loop in a compile time string and using a
mixin. Results are here:
Last time I checked, static foreach tended to load the index onto the
stack for each iteration even if it was never used. Did you take a look
at the ASM?
