There was a very lenghty discussion about this in the past. DMD is
correct on that one. The semantic is such as :

int plusEqual(ref int a, int b) {
  a = a + b;
  return a;
}

Could this be added to the spec please?

int main() {
    int sum=0;

    int return1_add9tosum() {
        sum += 9;
        return 1;

    sum += return1_add9tosum();
    return sum;
