Thank you for the help! That has clarified some things for me.

#!/usr/bin/env perl

open (my $data, "<", "test.txt") or die "There was a problem opening: 
+$!";
my @primers = <$data>;
close $data;
chomp @primers;
use strict; use warnings;
use Algorithm::Combinatorics qw(combinations);
my $strings = \@primers;
my $iter = combinations($strings, 2);
while (my $c = $iter->next) {
    print "@$c\n";
}

I'm now running this and it mostly does what I intended it to do. My output ends up putting an unwanted space in-between the 2 words that were combined. Is this because i'm stringifying?
