Modern Perl

“the world's best and most effective Perl programmers take full advantage of the CPAN to make up for missing language features, to improve their productivity, and because solving a problem once and for all and sharing it is the ultimate expression of laziness, impatience, and hubris”

Standard OO Perl:

package Person;

sub new { my ($class, %args) = @_; die(‘Name is required’) if !$args{name}; die(‘Name must be a string’) if ref $args{name}; return bless \%args, $class;}

sub hello { my ($self) = @_; print ‘Hi, my name is, ‘ . $self->{name} . “\n”;}

Modern OO Perl:

package Person;

use Moose;use MooseX::Method::Signature;

has ‘name’ => ( is => ’rw’, isa => ’Str’, required => 1,);

method hello { say ‘Hi, my name is, ‘ . $self->name();}
