         $object->my_dec;
         $object->my_dec;
         say $object->attr; ## ==> 8
         $object->my_dec( 5 );
         say $object->attr; ## ==> 3

   "inc( $amount? )"
       Arguments: Optional[Int].

       Increments the counter by $amount, or by 1 if no value is given.

         $object->my_inc;
         say $object->attr; ## ==> 2
         $object->my_inc( 3 );
         say $object->attr; ## ==> 5

   "reset()"
       Sets the counter to its default value, or 0 if it has no default.
