Shortcut for constructor
<p>Actually I don't know how to define this idioms.</p>

<p>In some code i have red something like:</p>

<pre><code>ClassWithAMessage c = "This is the message";
</code></pre>

<p>where i expected to read:</p>

<pre><code>ClassWithAMessage c("This is the message");
</code></pre>

<p>I don't know how to reproduce this behavior, can someone provide some information or a toy example?</p>
