Actually I am trying to go around it :) I choose to use the classes array because of the an ordering issue I encountered while trying to build an array of iptables rules : the template would get evaluated before some the classes would get the chance to add lines to the array. I'm hoping that by using the classes array (which is in its finale state before the classes start to run) I can avoid the ordering issue. my question was about the ruby syntax of checking for undefined out of scope variables (or are you trying to tell me that theres no way around it ?).
