That warning was default-silenced a few hours ago, which to me is a clear signal that this was not ready for public awareness yet. Indeed, I'm not willing to fix an obscure warning with no documented hints on how to get rid of it. In our case, both "value" and eg. "=" token names are used in parse_clause(). As bad as it might be, I'm relying on this behavior, so this is not just about adding random grouping to please PyParsing.
