I get Global symbol "@Arr" requires explicit package name , after I fix that up, I get

firstmessage
Output packed strings:
HASH(0xe0adb4)
HASH(0x13ae43c)
After reading file:
$VAR1 = [
          bless( {
                   'message' => 'firstmessage'
                 }, 'Note' ),
          bless( {
                   'message' => 'secondmessage'
                 }, 'Note' )
        ];
