  • Modern Perl Perl5
  • 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
