        # Example of using a hash instead of references
        my %data = (
            'name' => 'John Doe',
            'age' => 30,
            'occupation' => 'Developer',
        );

        # Accessing data directly from hash
        print "Name: $data{name}\n";  # Output: Name: John Doe
        print "Age: $data{age}\n";      # Output: Age: 30
        print "Occupation: $data{occupation}\n"; # Output: Occupation: Developer
