title: Can I map lists in Qt?
body: <p>This is already fairly concise, but it would be awesome if I could map the list a la Ruby. Say I have a <code>QStringList</code> <em>myStringList</em> which contains things like "12.3", "-213.0", "9.24". I want to simply map the whole thing using <code>toDouble</code> without having to iterate. Does Qt have a method for this?</p>
  
  <pre><code>// i.e. I would love a one-liner for the following
  // NB QT provices foreach
  QList&lt;double&gt; myDoubleList;
  foreach(QString s, myStringList) {
      myDoubleList.append(s.toDouble());
  }
  </code></pre>
