Safety is not what you think

[user1234 via Digitalmars-d-learn]

I want to share a stupid program to show you that D safety is 
more complex than you might think:

```d
module test;
void test() @safe
{
    int i;
    int b = (*&(*&++i))++;
}

void main() @safe
{
    test();
}
```

I'm not showing a deficiency of D, that program is undeniably 
safe ;)
