Nested namespaces
<p>I've got something like this:  </p>

<pre><code>namespace n1
{
    namespace n2
    {
        class foo{}
    }
}
</code></pre>

<p>In other file I write:</p>

<pre><code>using n1;
</code></pre>

<p>Why I can't type now something like:</p>

<pre><code>n2.foo smthing;
</code></pre>

<p>And how to make something like this possibile?</p>
