I don't think it's a good idea to include standard input for class methods, because then those functions couldn't be called without them waiting for input which there probably is none of. Anyway, here is my script: 
#!/usr/bin/perl
require '/home/me/perl/myclass.pl';
print "Enter your username: ";
chomp($username = <STDIN>);
print "Enter your password: ";
system("stty -echo");
chomp($password = <STDIN>);
system("stty echo");
print "\n";

$bot = new Myclass $username, $password;
if(!$bot->login){
        print "Enter your username: ";
        chomp($username = <STDIN>);
        print "Enter your password: ";
        system("stty -echo");
        chomp($password = <STDIN>);
        system("stty echo");
        print "\n";
}

my $action = {

        'do' => 'do_this',
        'change' => 'change_that'

};
print "Menu: ";
my $menu_item;
while(chomp($menu_item = <STDIN>) && $menu_item ne 'logout'){
        if (defined $action->{$menu_item}){
                my $method = $action->{$menu_item};
                $bot->$method;
        }else{
                print "I didn't understand the command.\n";
        }
        print "Menu: ";
}
if($menu_item eq 'logout'){
        $bot->logout;
}else{
        print "wtf?\n";
}

Basically, change_that is a subroutine/method of Myclass, and I want to pass arguments to it, using standard input. One way would be having change_that use <STDIN> in the actual code of the class, but that would be too unusable. Should I create a separate function for each item of $action? How would you wise Perl Monks do it in the cleanest and most efficient manner? If you need clarification, I would be happy. If you run my code you get a login prompt, then you are allowed to submit any command you want, until you say "logout." But lets say I use command "change that", which will call method "change_that", I want it to prompt the user for the data it needs to change.
