SYNOPSIS ^

  package Room;
  use Moose;

  has 'is_lit' => (
      traits    => ['Bool'],
      is        => 'rw',
      isa       => 'Bool',
      default   => 0,
      handles   => {
          illuminate  => 'set',
          darken      => 'unset',

      },
  );

  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
