This question is for both of you. I am creating a program that audits parameters for my company's network (about 250 million a day) and checks them against their compliance to a Golden Image. I am figuring out a set way to define ranges of appropriate and valid values and I believe that Set Notation is the best way. Problem is not only must I teach set notation to a bunch of analysts and engineers alike, I need to build a parser against it.

   Question is, has anyone done set notation compliance checking via the magic of perl before, and would you be willing to grace me with your insight.
