SYNOPSIS

         package Room;
         use Moose;

         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

DESCRIPTION

       This trait provides native delegation methods for boolean values. A boolean is a scalar
       which can be 1, 0, "", or "undef".

DEFAULT TYPE

       If you don't provide an "isa" value for your attribute, it will default to "Bool".

PROVIDED METHODS

       None of these methods accept arguments.

       ·   set

           Sets the value to 1 and returns 1.

       ·   unset

           Set the value to 0 and returns 0.

       ·   toggle

           Toggles the value. If it's true, set to false, and vice versa.

           Returns the new value.

       ·   not

           Equivalent of 'not $value'.
