I thought the code above was illegal at least in 2.059. I get an error 
unless I use goto case:

void main()
{
     int i;
     int j;

     switch (i) {
     case 0,1:
         goto case;  // goto, embraced by D :)

     case 2,3:
         j = 42;
         break;

     default:
         j = 43;
     }
}
