"But it seems daft to [force] you to copy the data to another instance"

I should have placed $self inside base instead, and allowed the subclasses to format it in some way - but i was trying to keep it simple. The idea is that the base clase contains the data in a Perl data structure and the subclasses are responsible for flitering that data structure into a particular format. Let me try again:

package Factory;

sub create {
   my $class = shift;
   my $obj = 'Base::' . shift;
   return $obj->new();
}

package Base;

sub new {
   my $class = shift;
   my $self = { thing => 'foo' };
   return bless $self,$class;
}

package Base::Bold;
use base 'Base';

sub output {
   my $self = shift;
   return '<b>' . $self->{thing} . '</b>';
}

package Base::Italic;
use base 'Base';

sub output {
   my $self = shift;
   return '<i>' . $self->{thing} . '</i>';
}

package main;

my @things = (
   Factory->create('Bold'),
   Factory->create('Italic'),
);

print $_->output,$/ for @things;

And an HTML resume is different than a PDF resume: HTML and PDF are adjectives to the noun resume - an adjective qualifies, distinquishes, and specifies - hence, an HTML resume is one kind of resume (Resume::HTML), and a PDF resume is another kind (Resume::PDF). I you don't like this, then how about naming them Resume::AsHTML and Resume::AsPDF instead? ;)
