Reduced more:

struct Matrix(T, uint N) {

    private static defaultMatrix() {
        T arr[N];
        return arr;
    }

    union {
        T[N] A = defaultMatrix;
        T[N] flat;
    }

    this(A...)(auto ref in A args) {
        uint k;

        foreach(ref v; args)
            flat[k++] = cast(T)v;
    }
}

enum S = Matrix!(int, 3)(1, 2, 3);
