Nah. Clearly this demonstrates the utility of a few "Boolean comparison" operators: 

    if $isFree ?= $isEasy
    if $isOne !?= $isOther

        unlink $dev
    eqv unlink $prod
    or  die "Inconsistent state";

         system $verifyUser
    neqv system $verifyAdmin
    or   die "You are not just either a User or an Admin";

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
