Maybe I'm missing the thing, but I'm not able to declare local

preferred design pattern?
```
int main()

int a = 1;
//ref int b = a; // Error: variable `tst_ref.main.b` only
parameters or `foreach` declarations can be `ref`
ref int b() { return a; }
b = 2;
assert(a == 2);
return 0;
}

Probably you are coming from C#. There are no reference variables
in D, but you can use pointers like in:
int* b = &a;
*b = 2;
