This SIMD code compiles, but it's not handy:
import core.simd;
void main() {
enum U = ubyte.max;
ubyte16 m = [U,U,U,U,U,U,U,U,U,U,U,U,U,U,U,U];
}
So maybe it's worth adding the ".max" and ".min" attributes to simd registers,
to allow:
import core.simd;
void main() {
auto a = ubyte16.max; // All initialized to ubyte.max.
auto b = int4.min; // All initizialized to int.min.
}
This also allows to write simd code that looks more like regular code.
