package MooseX::NonMoose::Meta::Role::Constructor;
use Moose::Role;
=head1 NAME
MooseX::NonMoose::Meta::Role::Constructor - constructor method trait for L<MooseX::NonMoose>
=head1 SYNOPSIS
package My::Moose;
use Moose ();
use Moose::Exporter;
Moose::Exporter->setup_import_methods;
sub init_meta {
shift;
my %options = @_;
Moose->init_meta(%options);
Moose::Util::MetaRole::apply_metaclass_roles(
for_class => $options{for_class},
metaclass_roles => ['MooseX::NonMoose::Meta::Role::Class'],
constructor_class_roles =>
['MooseX::NonMoose::Meta::Role::Constructor'],
);
return Class::MOP::class_of($options{for_class});
}
=head1 DESCRIPTION
This trait implements inlining of the constructor for classes using the
L<MooseX::NonMoose::Meta::Role::Class> metaclass trait; it has no effect unless
that trait is also used. See those docs and the docs for L<MooseX::NonMoose>
for more information.

# digging too deeply into it
