MooseX::UndefTolerant::Attribute - Make your attribute(s) tolerant to undef intitialization

VERSION

version 0.13

SYNOPSIS

package My:Class;
use Moose;

use MooseX::UndefTolerant::Attribute;

has 'bar' => (
    traits => [ qw(MooseX::UndefTolerant::Attribute)],
    is => 'ro',
    isa => 'Num',
    predicate => 'has_bar'
);

# Meanwhile, under the city...

# Doesn't explode
my $class = My::Class->new(bar => undef);
$class->has_bar # False!

DESCRIPTION

Applying this trait to your attribute makes it's initialization tolerant of of undef. If you specify the value of undef to any of the attributes they will not be initialized (or will be set to the default, if applicable). Effectively behaving as if you had not provided a value at all.
