PS :

I have done this :

     parallelContainer: while(true) {
     outer: foreach(i, a; parallel(array_of_a)) {
        foreach(j, b; parallel(array_of_b)) {
          auto c = myFunction0(i,j);
          auto d = myFunction1(a,b);
          auto f = myFunction2(i,b);
          auto g = myFunction3(a,j);

          if(someConditionCheck(c,d,f,g)) {
            break parallelContainer;
          }

        }
     break;
     }

Is this safe? Will this cause any problem that I can't foresee 
now? Thank you
