I have this code and wonder why it works this way with a '@' preceding the hash: 
#!/usr/bin/perl -w

use strict;
use Data::Dumper;

my %hash;
my @keys = qw ( one two three );
my @values = qw ( 1 2 3 );

#  What's with the @ symbol and not a $?
@hash{@keys} = @values;

print Dumper \%hash;

I'd expect it to be as below: 
#!/usr/bin/perl -w

use strict;
use Data::Dumper;

my %hash;
my @keys = qw ( one two three );
my @values = qw ( 1 2 3 );

#  I thought it would need a $!
$hash{@keys} = @values;

print Dumper \%hash;

Why do you need the '@' preceding the hash name and not a '$'?
