I understand. As for me, putting ";;; -*- lexical-binding: t -*-" is difficult. Because the file (.gnus.el or .emacs) isn't new. It consists of my code and the other parts that already exists. If I (or someone) put ";;; -*- lexical-binding: t -*-", the other parts will be influenced too. So I want to leave my code as it is. Thank you anyway. -- Satoshi Yoshida
