import std.algorithm;
import std.array;
import std.range;
import std.stdio;

void main(string[] args)
{
        auto data = [1,2,3];

        assert(data.cycle.take(5).array       == [1,2,3,1,2]);
        assert(data.retro.cycle.take(5).array == [3,2,1,3,2]);
}

This is why people should be using D instead of C++! This really needs
to get onto the D website somewhere.

how efficient is ufcs? It seems like it would be very slow in
general and way better to manually do the code. I wonder if
anyone has done any tests?
