      For empty documents, a la

      auto value = builder::stream::array{} << finalize;
      auto view = value.view();
      // view().begin() != view().end();
      

      This is because we don't check the return value of bson_iter_next() when we first initialize the iterator, so users can end up with invalid iterators.

      We should check the return value
