Mixup in hook_features_export_render() example

In the example hook_features_export_render() (in features.api.php,) the second-to-last line tries to implode $mycomponents, which doesn't exist in the context of the function:

<?php
function hook_features_export_render($module_name, $data, $export = NULL) {
  $code = array();
  $code[] = '$mycomponents = array();';
  foreach ($data as $name) {
    $code[] = "  \$mycomponents['{$name}'] = " . features_var_export(mycomponent_load($name)) .";";
  }
  $code[] = "return \$mycomponents;";
  $code = implode("\n", $mycomponents);
  return array('mycomponent_defaults' => $code);
}
?>

...
It should really be imploding $code:

-  $code = implode("\n", $mycomponents);
+  $code = implode("\n", $code);
