<p>I should mention for the specific case of Vala, I think you can write something like this:</p>

<div class="highlight highlight-source-vala"><pre><span class="pl-c">// some gobject in vala, to save typing</span>
<span class="pl-k">namespace</span> <span class="pl-en">Foo</span> {
  <span class="pl-k">public</span> <span class="pl-k">class</span> <span class="pl-en">Plugin</span> <span class="pl-k">:</span> <span class="pl-e">Object</span> {
    [<span class="pl-en">CCode</span>(<span class="pl-v">instance_pos</span>=<span class="pl-v">1</span>.<span class="pl-v">1</span>)]
    <span class="pl-k">bool</span> <span class="pl-en">init</span>(<span class="pl-k">Geany</span>.<span class="pl-k">Plugin</span> <span class="pl-v">p</span>) { <span class="pl-k">return</span> <span class="pl-c1">true</span>; }
    [<span class="pl-en">CCode</span>(<span class="pl-v">instance_pos</span>=<span class="pl-v">1</span>.<span class="pl-v">1</span>)]
    <span class="pl-k">void</span> <span class="pl-en">cleanup</span>(<span class="pl-k">Geany</span>.<span class="pl-k">Plugin</span> <span class="pl-v">p</span>) {}
  }
}</pre></div>

<p>It might work directly in this case.</p>
