I don't really understand the question. What is the confusion you are 
having?

Consider the `scope(exit)` rewrite:

```d
{
    someCode;
    scope(exit) close(foo);
    someCode;
}
```
This is equivalent to:
```d
{
    someCode;
    try { // new scope!
       someCode;
    } finally {
       close(foo);
    }
}
```

This introduces a new scope the same as a `with:` would introduce a new 
scope (and actually is simpler). Have you had confusion about that 
feature before? It makes perfect sense to me.
