    - speed up code that was accomodating ancient perl versions that are no

      This test seems like a footgun for release management reasons, but apprently
      I wasn't quite as careful as I tried to be in keeping the last release minimal.

    - Patch tests failing due to 5.25.1+'s deprecated unquoted { } in regex.
