title: Arrow function implicit return wrapped automatically with parenthesis
body: <p>I'm using Visual Studio Code with Prettier, and function like this:</p>
  
  <pre><code>(token: string) =&gt; this.token = token
  </code></pre>
  
  <p>becomes:</p>
  
  <pre><code>(token: string) =&gt; (this.token = token)
  </code></pre>
  
  <p>I think it's makes it less readable...
  Is there a a way to prevent this?</p>
