title: Making a variable global within a package
body: <p>I've searched the forum but can't find anything on this. I have the following line in a file by itself:</p>
  
  <pre><code>FormState = new ReactiveState();
  </code></pre>
  
  <p>Other files in the package can't reference FormState. How do I make it package-scoped instead of file-scoped?</p>
