package Room; use Mouse; has 'is_lit' => ( traits => ['Bool'], is => 'rw', isa => 'Bool', default => 0, handles => { illuminate => 'set', darken => 'unset', flip_switch => 'toggle', is_dark => 'not', }, ); my $room = Room->new(); $room->illuminate; # same as $room->is_lit(1); $room->darken; # same as $room->is_lit(0); $room->flip_switch; # same as $room->is_lit(not $room->is_lit); return $room->is_dark; # same as !$room->is_lit
