The meta module is an interesting idea - some mechanism for loading & keeping a list of potentially required modules. Perhaps something like this: 


package Foo;
use strict;
use warnings;

my $foo = Foo->new;

$foo->rarelyusedfunction;

Foo::CodeLoader->new->list();



sub new
{
        return bless \{},shift;
}

sub commonlyusedfunction
{
        # do stuff
}

sub rarelyusedfunction
{
        my $self = shift;
        my $cl = Foo::CodeLoader->new();

        $cl->load('DDS');

        my $dds = Data::Dump::Streamer->new;
        $dds->Dump($self)->Out();

}

package Foo::CodeLoader;

sub new
{
        my $class = shift;
        my %modules = (      DDS        =>      'Data::Dump::Streamer'
+    );
        return bless \%modules,$class;
}

sub load
{
        my $self = shift;
        my $param = shift;
        eval "require $self->{$param}";
}

sub list
{
        my $self = shift;
        for (values %{$self})
        {
                print "$_\n";
        }
}
