Just a random example using Zydeco...

use Zydeco prefix => 'App';

class Car {
    has name  ( type => Str );
    has price ( type => Num );
    has speed (
        type         => Num,
        default      => 0,
        handles_via  => 'Number',
        handles      => {
            speed_up    => 'add',
            slow_down   => 'sub',
        },
    );
    
    my $count;
    method BUILD    { ++$count }
    method DEMOLISH { --$count }
    method count    { $count }
}

my $red_car  = App->new_car( name => 'Red' );
my $blue_car = App->new_car( name => 'Blue' );

$red_car->speed_up( 25 );
$red_car->speed_up( 10 );

say $red_car->speed;
say App::Car->count;
