First of all, there is no such thing as a global region in D. 
Although the addresses are different, we have 2 regions:
* **AAA:** Stack
* **BBB:** Heap

Yes, there are a lot of expressions: ```static, const, immutable, 
shared etc.``` But the expressions matters to D compiler. Two 
concepts are important to us: the inter-module region and the 
```main()``` function where the code starts to run.

Please paste the following into the inter-module region. Turn it 
on/off with the toggle (//) sign and see the difference.

```d
//auto data = iota(1024).array; /*

int[] data;
static this() {
   data = new int[1024];
} //*/

void main()
{
   writefln("%12x, %12x", &data[0], &data[$-1]);
}
```
