14. Perl 5: The Big Nouns
• Compatibility • Maintainability
• Extensibility • Portability
• Usability • Responsibility
• Reusability • Embeddibility
• Readability • Respectability?
• Scalability

18. Modern Perl
Perl5

19. Modern Sense

20. Best Practices

Conway

24. Clear Semantic
Trivial to Understand

26. Moose
Postmodern OO /

27. 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);
}

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

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

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

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

32. 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);
}
}

33. Extendibility

34. Self-Modifying Perl

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

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

37. WHY ?
• / Augmented Syntax
• / Extended Semantic

38. As a modern Perl
programmer...
