This was about the fact that slices were a stopper for a D .net 
implementation.

The direct translation of the code here 
(https://dlang.org/articles/d-array-article.html#introducing-slices) is:

int[] a = new int[5];
var b = new ArraySegment<int>(a, 0, 2);
var c = new ArraySegment<int>(a, 3, 2);
c[0] = 4;
c[1] = 5;
c.CopyTo(b);

Surprise, the a content is the same as in D - [4,5,0,4,5].

I will stop my fallacy here, I promise this is the last post 
bragging about array segments, I feel some tension piling up on D 
forums and I don't want to contribute to it. My mistake was the 
use of the word "exactly".
