<p>In <a href="https://github.com/mlpack/mlpack/pull/686#discussion_r66366961">src/mlpack/methods/ne/gene.hpp</a>:</p>
<pre style='color:#555'>&gt; +
&gt; +  // Destructor.
&gt; +  ~LinkGene() {}
&gt; +
&gt; +  // Get aFromNeuronId.

<p><a href="https://github.com/zoq" class="user-mention">@zoq</a> So in this way, linkGene.Weight() get the weight, and linkGene.Weight() = weight set the member weight, is this correct?</p>

<p>I can change them into this style. But just a little bit  curious, what is the main benefit of this format? (compared with Weight() getter and Weight(weight) setter)</p>
