Inside the `Person` Class

        package Person;

        sub new {
          my ($class) = @_;
          my $self = { };
          bless $self, $class;
          return $self;
        }

This constructs a new Person object
The object itself is an empty anonymous hash
bless turns a Perl data structure into an object
- It is like putting a sticky label on the object with the class name on it
Before: $self is just a regular hash
After: It is still a hash, but also an object in class $class
Recall that Person->new is like Person::new('Person')
$class here is Person
