--- Comment #1 from Dennis <dkorpel at live.nl> ---
It's not that obvious, checking nothrow is not enough. This is not allowed:

```
void main () @safe @nogc nothrow
{
    try {
        scope exc = new Exception("Baguette");
        throw exc;
    } catch (Exception e) {
        assert(e is exc);
    }
}
```

There needs to be a check whether the try-catch block that catches the
exception is inside the scope of the variable that is being thrown.
