+ * 3.3 CHANMODES
+ *
+ * o CHANMODES=A,B,C,D
+ *
+ * The CHANMODES token specifies the modes that may be set on a channel.
+ * These modes are split into four categories, as follows:
+ *
+ * o 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.
+ * o Type B: Modes that change a setting on the channel. These modes
+ * always take a parameter.
+ * o 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.
+ * o Type D: Modes that change a setting on the channel. These modes
+ * never take a parameter.
+ *
+ * If the server sends any additional types after these 4, the client
+ * MUST ignore them; this is intended to allow future extension of this
+ * token.
+ *
+ * The IRC server MUST NOT list modes in CHANMODES which are also
+ * present in the PREFIX parameter; however, for completeness, modes
+ * described in PREFIX may be treated as type B modes.
