You can use a hash as a set or a bag.
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
# Make Data::Dumper pretty
$Data::Dumper::Sortkeys = 1;
$Data::Dumper::Indent = 1;
# Set maximum depth for Data::Dumper, zero means unlimited
$Data::Dumper::Maxdepth = 0;
my @a = qw( a b c x y z a b );
my %set = map { $_ => 1 } @a;
print '%set : ', Dumper \%set;
my %bag = ();
$bag{$_} ++ for @a;
print '%bag : ', Dumper \%bag;
__END__

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
