title: (how) can I make a whole package private in scala
body: <p>I would like to make all content of a package private to be usable only inside its library, without having to add <code>private[...]</code> to all classes and objects.
  So I tried to make the package object private:</p>
  
  <pre><code>package org.whatever
  
  private[whatever] package object internalstuff
  </code></pre>
  
  <p>But the compiler didn't like that (expected start of definition...).</p>
  
  <p>How could I do that?</p>
