title: scala type inference with _ place holder
body: <pre><code>List("This","is","Scala").foreach(a =&gt; print(a+" "))
  </code></pre>
  
  <p>compiles fine, but</p>
  
  <pre><code>List("This","is","Scala").foreach(print(_+" "))
  </code></pre>
  
  <p>fails complaining of missing parameter type. I couldn't figure out why it fails.</p>
  
  <p>EDIT: I meant print not println - not that it makes logical difference.</p>
