=head1 ERRORS

 new():
         From Mo::utils::check_array_object():
                Glosse isn't 'Wikibase::Datatype::Value::Monolingual' object.
                Parameter 'glosses' must be a array.
                Parameter 'statements' must be a array.
                Statement isn't 'Wikibase::Datatype::Statement' object.
         From Mo::utils::check_number_of_items():
                Glosse for language '%s' has multiple values.
