Constructors

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

• Usually you will see shorter versions of this:

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

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

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

• Sometimes you may see bless {} => $class
