Associative multidimensional Arrays

[MaB]

Hi!

I want to bulid up a IndexArray with a structure like this (PHP 
code):
<code>
$arrIndex = array(
  "A" => array(
           "B" => array()
         ),
  "B" => array(
           "B" => array("C" => array())
         )

);
</code>
The Keys are of Type string and the values can be arrays with the 
same structure.
The Array-Depth has to be variable..
Is there a way in D to make it possible? I am trying it now since 
hours :(

Greetings
