What if i wanted to to have both private and public variables inside a perl module? I cant return a hash with closure reference as one of its members as the object? if i do that then the user can call the closure subroutine directly and access the variables.. lemme start with a real time example.. say i have 3 variables a,b,c and a STATE variable. The user can manipulate a,b,c but the state will be decided by the class itself. How can i implement this class?
