#pod =head1 SYNOPSIS
#pod
#pod package Foo;
#pod
#pod use Moose;
#pod use MooseX::LazyRequire;
#pod
#pod has foo => (
#pod is => 'ro',
#pod lazy_required => 1,
#pod );
#pod
#pod has bar => (
#pod is => 'ro',
#pod builder => '_build_bar',
#pod );
#pod
#pod sub _build_bar { shift->foo }
#pod
#pod
#pod Foo->new(foo => 42); # succeeds, foo and bar will be 42
#pod Foo->new(bar => 42); # succeeds, bar will be 42
#pod Foo->new; # fails, neither foo nor bare were given
#pod
#pod =head1 DESCRIPTION
#pod
#pod This module adds a C<lazy_required> option to Moose attribute declarations.
#pod
#pod The reader methods for all attributes with that option will throw an exception
#pod unless a value for the attributes was provided earlier by a constructor
#pod parameter or through a writer method.
#pod
#pod =head1 CAVEATS
#pod
#pod Prior to Moose 1.9900, roles didn't have an attribute metaclass, so this module can't
#pod easily apply its magic to attributes defined in roles. If you want to use
#pod C<lazy_required> in role attributes, you'll have to apply the attribute trait
#pod yourself:
#pod
#pod has foo => (
#pod traits => ['LazyRequire'],
#pod is => 'ro',
#pod lazy_required => 1,
#pod );
#pod
#pod With Moose 1.9900, you can use this module in roles just the same way you can
#pod in classes.

=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.
