title: render json and return
body: <p>How could we call <code>and return</code> after each <code>render json: @object</code> by default (automatically)</p>
  
  <p>What I do now,</p>
  
  <pre><code>def not_authorized(msg="Not Authorized")
  render json: msg, status: 401
  end
  </code></pre>
  
  <p>In Controller call..</p>
  
  <pre><code>not_authorized and return
  </code></pre>
  
  <p>or</p>
  
  <pre><code> render :json =&gt; @user and return
  </code></pre>
  
  <p>So..</p>
  
  <ol>
  <li><p>Can we make <code>and return</code> implicit when calling render json? </p></li>
  <li><p>Why isn't this the default i.e what's the purpose of not returning after a <code>render</code> or more specifically a <code>render json:</code>?</p></li>
  </ol>
