Its been about a decade since many IRCds have implemented the mode extension +q (quiet) to compliment channel +beI (ban exempt Invite) lists. It is in popular use among many large (including freenode) networks.

Please add $iql() to go along with $ibl $iel $iIl
Please add isquiet to go with isban isexempt isinvite

Without these, it is difficult for my scripts to determine whether a user is allowed to act in a channel.

Thanks.
