Ah! The subroutine only returns a hash reference, like the following:

use strict;
use warnings;
use Data::Dumper;

my $hashRef = getHashRef();

print Dumper \$hashRef;
print $hashRef->{'Hello'};

sub getHashRef {
    my $hwwns;
    $hwwns->{'Hello'} = 'world!';
    return $hwwns;
}

Output:

$VAR1 = \{
            'Hello' => 'world!'
          };
world!
