This allows to pass a QueryObject (_Callable) to the scope definition. refs: * https://github.com/rails/rails/blob/v6.0.6.1/activerecord/lib/active_record/scoping/named.rb#L171 * https://github.com/Selleo/pattern/blob/master/lib/patterns/query.rb * https://takaokouji.github.io/output/query-object/ (Japanese)
