    $default[$name] = $data[$name] = $default_value;

  // Reset all: ($name == NULL). This needs to be done one at a time so that
  // references returned by earlier invocations of drupal_static() also get
  // reset.
  foreach ($default as $name => $value) {

  }

  // As the function returns a reference, the return should always be a
  // variable.
