There is one more thing that I have forgotten. If you have code like:
void main() {
double[8] a = 0.5;
double[8] b = 2.0;
double r = dot5(a, b);
}
then you can't be sure that 'a' and 'b' are aligned to 16 bytes (I hope they
are aligned to 8).
Time ago I have suggested the simple syntax:
align(16) double[8] b = 2.0;
but things are not so easy:

No need to worry about that. Unaligned arrays can be handled simply by
taking care of the stray elements by hand. The bulk of the loop will run
at full speed.
