Modern Sense

Best Practices

Clear Semantic
Trivial to Understand

Moose
Postmodern OO /

package Point;
use Moose;
has 'x' => (is => 'rw', isa => 'Int');
has 'y' => (is => 'rw', isa => 'Int');
sub clear {
my $self = shift;
$self->x(0);
$self->y(0);
}

package Point3D;
use Moose;
extends 'Point';
has 'z' => (is => 'rw', isa => 'Int');
after 'clear' => sub {
my $self = shift;
$self->z(0);
};

package Point3D;
use Moose;
extends 'Point';
has 'z' => (is => 'rw', isa => 'Int');
after 'clear' => sub {
my $self = shift;
$self->z(0);
};

package Point3D;
use Moose;
extends 'Point';
has 'z' => (is => 'rw', isa => 'Int');
after 'clear' => sub {
my $self = shift;
$self->z(0);
};

package Point3D;
use Moose;
extends 'Point';
has 'z' => (is => 'rw', isa => 'Int');
after 'clear' => sub {
my $self = shift;
$self->z(0);
};

use MooseX::Declare;
class Point {
has 'x' => (is => 'rw', isa => 'Int');
has 'y' => (is => 'rw', isa => 'Int');
method clear {
$self->x(0);
$self->y(0);
}
}

Extendibility

Self-Modifying Perl

App->start {
say "Hello";
};
Not-really valid Perl5

App->start(sub {
say "Hello";
});
Valid Perl5

WHY ?
• / Augmented Syntax
• / Extended Semantic
