title: Alias a variable in Unity C#
body: <p>I am looking for a way to declare an alias for a variable in Unity C#.<br />
  For example, in the following code:</p>
  <pre><code>struct Data
  {
    int value;
  }
  
  class Instance
  {
    private Data data;
    public int value =&gt; data.value;
  }
  </code></pre>
  <p>The <code>=&gt;</code> operator provides a <strong>read-only</strong> variable. I'm looking for a way to declare a variable that I can read <strong>and</strong> write to.
  In C++ I would use the <code>using</code> keyword but that doesn't seem to work the same way in C#.</p>
  <p>Any help would be appreciated, thanks!</p>
