title: Implicit keyword before a parameter in anonymous function in Scala
body: <p>I understand implicit parameters and implicit conversions in Scala but I saw this for the first time today: the implicit keyword in front of a parameter in an anonymous function:</p>
  
  <pre><code>Action { implicit request =&gt;
    Ok("Got request [" + request + "]")
  }
  </code></pre>
  
  <p>What does the implicit keyword do here?</p>
  
  <p>Are there resources on the web that describes more on what the use case is?</p>
