SUPER is a class that controls the superclass of the current class.
Look here: http://search.cpan.org/~chromatic/SUPER-1.17/lib/SUPER.pm
So, what that means is, run the encrypt method/subroutine/function of
the superclass of the current class. Something I would highly
recommend is dive into Beginning Perl write a load of just little
programs that maybe are useful or maybe not. For example, write a
program that lets you experiment with regular expressions, by taking a
string input and then taking an expression input then see if it
matches.
