I need to write some more complicated perl5 code and would like to learn some perl OO. I am familiar with the OO-concept from other languages.

If I would like to make an object that has one instance variable I can do it in this way accoring to the book "Learning Perl Objects, References & Modules" :
my $name = "Mr. Ed";
my $tv_horse = \$name;
bless $tv_horse, "Horse";

[download]
However to make an object with two variables the book uses a hash..: 
my $lost = bless { Name => "Bo", Color => "white" }, Sheep;

[download]
This is intresting becouse it could mean that I can not have an perl5-object with more then one instance variable without using a hash. So how do you do if you would like to make an object that contains arrays, hashes and different many different instance variables? If you really have to create a complex datastructure to store all this, and then bless it much of the benefits with using objects will disepear. So is it possible to bless many different variables, arrays and hashes to the same object or how do you do?

I also wonder if you know which state of development perl 6 is in? Is in possible to use for production even if has not officially been released yet or is it still to incomplete and full of bugs?
