The reverse is also possible and note that .capacity is 0 in any 
case.

```d
// D 2.0.83

import std.stdio;
void main()
{
   int[4] abcd = [0, 1, 2, 3];
   int[] slice = abcd[];
   slice.writeln(": ", slice.capacity);

   int[] dcba = [ 7, 6, 5, 4, 3, 2, 1, 0];
   int[4] arr = dcba[4..$];
   arr.writeln(": ", arr.capacity);

   arr = dcba[0..4];
   arr.writeln(": ", arr.capacity);
}/*

   [0, 1, 2, 3]: 0
   [3, 2, 1, 0]: 0
   [7, 6, 5, 4]: 0

Process finished.
