mir.ndslice : multi dimensional associative array - Example/Docs

[Vino via Digitalmars-d-learn]

Hi All,

  Is it possible to create a multi dimensional associative array 
using mir.ndslice,
  if yes,
   (1): request you to point me to some example / docs
   (2): below is an example multi dimensional associative array 
using the core d module, and
        how can we to implement the same using mir.ndslice.
   (3): What are the pros and cons of using mir.ndslice over the 
core d module.

import std.stdio;
void main () {
   string[int][string] aa;
   aa["Name"] = [1: "test01", 2:"test02"];
   aa["Pool"] = [1: "Development", 2:"Quality"];
   foreach(i; aa["Pool"].byValue) { writeln(i); }     
}

From,
