A hash reference is a scalar created using the \ operator as follows:

 
my %user;
$user{'name'}    = "hatter";
$user{'network'} = "irc.blackhatacademy.org";
 
my $hashref = \%user;
 

Once you've created a hashref (hash reference) you must use pointers to access a key:

 
print $user->{'name'} . "\n";
print $user->{'network'} . "\n";
