=head1 NAME

MooseX::LazyRequire - Required attributes which fail only when trying to use them

=head1 VERSION

version 0.11

=head1 SYNOPSIS

package Foo;

use Moose;
    use MooseX::LazyRequire;

has foo => (
        is            => 'ro',
        lazy_required => 1,
    );

has bar => (
        is      => 'ro',
        builder => '_build_bar',
    );

sub _build_bar { shift->foo }

Foo->new(foo => 42); # succeeds, foo and bar will be 42
    Foo->new(bar => 42); # succeeds, bar will be 42
    Foo->new;            # fails, neither foo nor bare were given

=head1 DESCRIPTION

This module adds a C<lazy_required> option to Moose attribute declarations.

The reader methods for all attributes with that option will throw an exception
unless a value for the attributes was provided earlier by a constructor
parameter or through a writer method.

=head1 CAVEATS

Prior to Moose 1.9900, roles didn't have an attribute metaclass, so this module can't
easily apply its magic to attributes defined in roles. If you want to use
C<lazy_required> in role attributes, you'll have to apply the attribute trait
yourself:

has foo => (
        traits        => ['LazyRequire'],
        is            => 'ro',
        lazy_required => 1,
    );

With Moose 1.9900, you can use this module in roles just the same way you can
in classes.
