That's a bit dangerous isn't it?

#!/usr/bin/perl

use strict;
use warnings;

my @car  = ('a', 'b,c');
my @cond = ('a', 'b', 'c');


if(join(',', @car) eq join(',', @cond)) {
  print "FOUND\n";
}
else {
  print "NOT FOUND\n";
}

This indicates that the arrays are the same even tho', clearly, they aren't.

If you're going to use code like this you have to know what are valid characters in your input arrays and be very careful in choosing your join string.
