=head1 NAME
MooseX::StrictConstructor::Trait::Method::Constructor - A role to make immutable constructors strict
=head1 VERSION
version 0.21
=head1 DESCRIPTION
This role simply wraps C<_generate_BUILDALL()> (from
C<Moose::Meta::Method::Constructor>) so that immutable classes have a
strict constructor.
=head1 SUPPORT
Bugs may be submitted at L<https://github.com/moose/MooseX-StrictConstructor/issues>.
I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
