title: Can't gain the `pipeTo` method on [[scala.concurrent.Future]]
body: <p>As the doc of akka explains, you should be able to gain the <code>pipeTo</code> method on [[scala.concurrent.Future]] this way:</p>
  
  <pre><code>import akka.pattern.pipe
  val future = ...
  future pipeTo sender()
  </code></pre>
  
  <p>Unfortunately, I can't do that, i'm getting an error "can't resolve symbol pipeTo" in my IDE.</p>
  
  <p>As a workaround, I had to use the syntax this way  </p>
  
  <pre><code>pipe(future) pipeTo sender()
  </code></pre>
  
  <p>But it still disturb me to not figure out why (i'm quite newby in scala BTW). Thanks a lot to help understand this puzzle.</p>
  
  <p>scala 2.12.2
  akka 2.5.3</p>
