Here's a handy little algorithm I found in my extremely dusty mIRC folders.

on *:INPUT:#:{ if ($regex($left($1,2),[-+][a-zA-z])) { mode $chan $1 $eval($iif(!$2,$str($+($me,$chr(32)),$regex($1,/[ohv]/g)),$2-),10) } }

It'll allow mode evaluation for valid shorthand expressions. Triggered by using "+" or "-" accompanied by a mode value and parameters.

+b ~q:*@*.*
