void main() {
    int[2][] data1;
    data1.length++;
    int[2] r1 = true ? data1[0] : [0, 0]; // OK, no cast needed

    int[2][][] data2;
    data2.length++;
    int[2][] r2 = true ? data2[0] : [cast(int[2])[0, 0]]; // OK
    int[2][] r3 = true ? data2[0] : [[0, 0]]; // error

    int[2][][][] data3;
    data3.length++;
    int[2][][] r4 = true ? data3[0] : [[cast(int[2])[0, 0]]]; // OK
