[Python-Dev] SC 2020 recommendation for PEP 634

After much deliberation, the 2020 SC will be making a recommendation to the 2021 SC to accept PEP 634 (although this was not a unanimous decision). This is in no way a binding recommendation to the 2021 SC (even if a majority of current council members get re-elected), but we felt we should pass on our thoughts to the next council as we have been discussing pattern matching for a few months at this point and we promised we would make some decision to the PEP authors.
