The behaviour of smart match on arrays may well change in Perl 5.18 or 5.20.

This works quite nicely for me...

use strict;
use warnings;
use File::Slurp qw( slurp );
use Syntax::Keyword::Junction qw( any );

my @first  = map { lc($_) } slurp('file1.txt');
my @second = map { lc($_) } slurp('file2.txt');

chomp(@first, @second);

print "Machines extra in second list...\n";

for my $machine (@second)
{
    if ($machine eq any(@first)) {
        print "$machine is already there\n";
    }
    else {
        print "$machine is new\n";
    }
}
