<p>For when through2 is just too verbose :wink:</p>
<p>Note you will <strong>NOT</strong> be able to skip chunks. This is intended for modification only. If you want filter the stream content, use either <code>through2</code> or <code>through2-filter</code>.</p>
<p><strong>IMPORTANT:</strong> If you return <code>null</code> from your function, the stream will end there.</p>
