title: Writing To The Response in Rails? (Like "echo" in PHP)
body: <p>I know that I can do this in Rails:</p>
  
  <pre><code>&lt;%="hello" %&gt;
  </code></pre>
  
  <p>but is there any way to do this</p>
  
  <pre><code>&lt;%
  echo "hello"
  %&gt;
  </code></pre>
  
  <p>and get it to show up in the response?</p>
