What is the most efficient way of implement a rotation of ubyte[4] array?
By rotation I mean: rotateRight([1, 2, 3, 4]) - [4, 1, 2, 3]
TIA,
Tom;

Two versions, I have done no benchmarks so far:
import std.c.stdio: printf;
union Four {
ubyte[4] a;
uint u;
}
void showFour(Four f) {

I don't know of anything more efficient than:
ubyte[4] bytes = [1,2,3,4];
bytes = bytes[$-1] ~

I'm stunned that this works. I'd even consider reporting it as a bug. You're
concatenating a ubyte[] ont a
