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 provides a simple boolean attribute, which supports most of the basic math operations.

PROVIDED METHODS

These methods are implemented in Moose::Meta::Attribute::Native::MethodProvider::Bool. It is important to note that all those methods do in place modification of the value stored in the attribute.
set
Sets the value to 1.
unset
Set the value to 0.
toggle
Toggles the value. If it's true, set to false, and vice versa.
not
Equivalent of 'not $value'.
