Package List;

has content => (is=>'ro', required=>1);
has items => (is=>'ro', required=>1, isa=>ArrayRef);

sub process {
  $self->for('#content_area') => sub {
    $self->content->repeat($self->items); 
  };
}

sub template {
  return q[
    <ul>
      <li id='content_area'/>
    </ul>
}

package PersonItem;

extends 'ListItem';

Basically any component that wants to have its content repeat needs to inherit from List component and that will automatically do the repeat for you.
