  static $in_username_alter = FALSE;
  $uid = $account
    ->id();

  // Don't alter anonymous users or objects that do not have any user ID.
  if (empty($uid)) {

  // Real name was loaded/generated via hook_user_load(), so re-use it.
  if (isset($account->realname)) {

      // Only if the real name is a non-empty string is $name actually altered.
      $name = $account->realname;
    }

  // Real name was not yet available for the account so we need to generate it.
  // Because tokens may call format_username() we need to prevent recursion.

    // If $account->realname was undefined, then the user account object was
    // not properly loaded. We must enforce calling user_load().
