#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'.
