What everyone else said, but you can get a pointer with 'in'

void main() {
    uint[][uint] aa;
        
    aa[5] = new uint[0];
    auto temp = 5 in aa; // copy uint[] reference
    *temp ~= 1;
        
    assert(temp.length == 1 && (*temp)[0] == 1); // pass
    assert(aa[5].length == 1 && aa[5][0] == 1); // pass

}
