title: How does one access `$global` or `out.global` in non-top-level components in MarkoJS?
body: <p>I'm trying to access global variables from a Marko component, but I'm getting <code>Uncaught ReferenceError: out is not defined</code>.</p>
  
  <pre><code>class {
      onClick(event) {
          console.log(out.global.message)
          event.preventDefault()
      }
  }
  </code></pre>
  
  <p>Shouldn't <code>out.global</code>/<code>$global</code> be accessible everywhere?</p>
