# ABSTRACT: A role to make immutable constructors strict
=pod
=head1 NAME
MooseX::StrictConstructor::Role::Meta::Method::Constructor - A role to make immutable constructors strict
=head1 VERSION
version 0.10
=head1 SYNOPSIS
Moose::Util::MetaRole::apply_metaroles(
for_class => $caller,
class => {
constructor =>
['MooseX::StrictConstructor::Role::Meta::Method::Constructor'],
},
);
=head1 DESCRIPTION
This role simply wraps C<_generate_BUILDALL()> (from
C<Moose::Meta::Method::Constructor>) so that immutable classes have a
strict constructor.
