Instead of

 use utf8;
 use strict;
 use warnings;
 use Moose::Util::TypeConstraints qw(enum);
 use MooseX::SemiAffordanceAccessor;
 use MooseX::Params::Validate qw(pos_validated_list);
 use Treex::Core::Log;
 use Treex::Core::Config;
 use Treex::Core::Resource;
 use Treex::Core::Types;
 use Treex::Core::Files;
 use List::MoreUtils qw(all any first_index);
 use List::Util qw(first);
 use Scalar::Util qw(weaken);
 use Readonly qw(Readonly);
 use Data::Dumper qw(Dumper);


=head1 SUBROUTINES

=over

=item $language_name = get_lang_name($iso639_code)

=item $bool = is_lang_code($iso639_code)

=item pos_validated_list

This subroutine is automatically exported. Depending on the value of 
L<$Treex::Core::Config::params_validate|Treex::Core::Config/params_validate> 
it is either the (slow) one from 
L<MooseX::Params::Validate> or a fast one, that does 
no type checking.
