Can't these kinds of errors be eliminated by using foreach loops?:

```d
     Square[8][8] square;
     foreach (int i, ref v; square)
     {
         foreach(int j, ref w; v)
         {
             if((isEven(i)&&isEven(j))^(!isEven(i)&&!isEven(j)))
                 w = new Square(Color.none, sColor.white);
             else 
if((!isEven(i)&&isEven(j))^(isEven(i)&&!isEven(j)))
                 w = new Square(Color.none,sColor.black);
             else
                 assert(false);

         }
     }
```
