title: scala - dispatch example not working
body: <p>I'm following the very first example in the <a href="http://dispatch.databinder.net/Dispatch.html" rel="nofollow">dispatch</a>docs - </p>
  
  <pre><code>    val svc = url("http://api.hostip.info/country.php")
      val country = Http(svc OK as.String)
      for (c &lt;- country)
        println(c)
  </code></pre>
  
  <p>I do not get any output printed. When I change it to below to make blocking call then I get the output.</p>
  
  <pre><code>val res = country()
  println(res)
  </code></pre>
  
  <p>Need help with this.</p>
  
  <p>Full program-</p>
  
  <pre><code>import dispatch._
  object DispatchTest {
  
    def main(args: Array[String]) {
      val svc = url("http://api.hostip.info/country.php")
      val country = Http(svc OK as.String)
      for (c &lt;- country)
        println(c)
    }
  }
