  }

  // Interpret the last arg as a distance, if it is numeric.

    ->getDefaultDist();
  $address = implode(', ', $args);
  if (!empty($address) && module_exists('geocoder')) {
    $all_geocoder_engines = array_keys(geocoder_handler_info('text'));

    // Pick Google if defined, otherwise the first in the list.
    $geocoder_engine = in_array('google', $all_geocoder_engines) ? 'google' : reset($all_geocoder_engines);
    if ($geocoded_data = geocoder($geocoder_engine, $address)) {
      return array(
        'latitude' => $geocoded_data
          ->getY(),
        'longitude' => $geocoded_data
          ->getX(),
