I really don&#x27;t have any idea what you are talking about..<p>Are you talking about something like this:<p><pre><code>  $hash_of_hash = {
    hash1 =&gt; {key1 =&gt; &#x27;value1&#x27;},
    hash2 =&gt; {key1 =&gt; &#x27;value1&#x27;}
  };
  say $hash_of_hash-&gt;{hash1}{key1};
</code></pre>
Seems easy to me...<p>I think reference syntax in Perl6 is gone. Which personally I don&#x27;t like.
