title: JSweet generates __class, which gives an error in the tTypescript compiler
body: <p>If I generate Typescript based on Java class, below the created Typescript class the following is generated:</p>
  <p><code>Department[&quot;__class&quot;] = &quot;org.test.Department&quot;;</code></p>
  <p>Compiling it gives:
  <code>TS7053: Element implicitly has an 'any' type because expression of type '&quot;__class&quot;' can't be used to index type 'typeof Department'. Property '__class' does not exist on type 'typeof Department'.</code></p>
  <p>Why is this generated, and why does it break the Typescript compile?</p>
  <p>Best,</p>
  <p>JG</p>
