Code that need to be repeated in many places with virtually no modifications, to the point where its creation can be automated.

Illustration

As an example, take writing a class in Language:Perl:

package Company; # class declaration
use strict;
use warnings;

# constructor needs to be written manually
sub new {
    my $class = shift;
    # creating hash with default arguments
    my $mess  = {
        children => [],
        @_
    };
    # checking for required arguments
    die 'No name given' if not $mess->{name};
    # creating an object
    return bless $mess => $class;
}

# accessors need to be written manually
sub name {
    my ($self, $new_name) = @_;
    if ($new_name) {
        return $self->{name} = $new_name;
    } else {
        return $self->{name};
    }
}

sub children {
    my ($self, $new_children) = @_;
    if ($new_children) {
        return $self->{children} = $new_children;
    } else {
        return $self->{children};
    }
}

Since no sane person would do this for every class and every accessor, there are ways to automate this process. In fact, the system is designed to be automated.

For example, using Technology:Moops:

use Moops;

class Company {
    has 'name'     => (is => 'rw', required => 1         );
    has 'children' => (is => 'rw', default  => sub { [] });
}

These few lines remove the need of all the boilerplate seen above.
