+ *
+ * Type A: Modes that add or remove an address to or from a list.
+ * These modes always take a parameter when sent by the server to a
+ * client; when sent by a client, they may be specified without a
+ * parameter, which requests the server to display the current
+ * contents of the corresponding list on the channel to the client.
+ *
+ * Type B: Modes that change a setting on the channel. These modes
+ * always take a parameter.
+ *
+ * Type C: Modes that change a setting on the channel. These modes
+ * take a parameter only when set; the parameter is absent when the
+ * mode is removed both in the client's and server's MODE command.
+ *
+ * Type D: Modes that change a setting on the channel. These modes
+ * never take a parameter.
