Most situation requires to handle explicitly the control-flow when you touch the structure. For example try to loop interchange:

```
for ( ) @outer {
  for ( ) @inner { 
    if (something) break @outer;
  }
}
```

Having a symbol here makes its so that you can **syntactically** just do it without caring about the break, but it would be just wrong to do so.
