auto arr = [1, 2, 3] should be a static array, not a GC allocated array

`auto` is like a politician speaking with big promises. Unless 
you explicitly state it, you have to accept its choice. For 
example:

```d
void main()
{
   alias type = int[3];
   auto arr = cast(type)[1, 2, 3];
   assert(is(typeof(arr) : type));
}
```
It usually chooses int for numbers, its arrays are dynamic.
