Yes, there is. One way is to remember the id of the last post in a chunk and pass it as the 'after' parameter to fetch_links(). Here is an example fetching post titles in chunks of size 25 (though, any size up to 100 will, of course, work):

use strict;
use warnings;
use feature 'say';
use Reddit::Client;

my $subreddit    = '/r/perl';
my $limit        = 25;
my $reddit       = Reddit::Client->new(user_agent => 'MyApp/1.0');

my $last_post;
foreach my $page (1 .. 8) {
    my $links = $reddit->fetch_links(
        subreddit => $subreddit,
        limit     => $limit,
        after     => $last_post
    );
    foreach my $link (@{ $links->{items} }) {
        say $page, ': ', $link->{title};
    }
    $last_post = $links->{items}->[-1]->{name};
}
