D can break on labels, which is even more powerful than that. To 
be honest, I don't recall ever using it in my own code, but it 
works.

```d

import core.stdc.stdio: printf;

void main()
{
     outer: for (size_t i = 0; i < 4; i++) {
         for (size_t j = 0; j < 4; j++) {
             if (i * j > 4) {
              	break outer;
             }
          	printf("i = %lu, j = %lu\n", i, j);
         }
         printf("i = %lu\n", i);
     }
}
```
