Unfortunately the patch doesn't actually apply due to binary
characters in the diff, not quite sure the magic incantation to
make that work, so I recommend replacing src/gnu/usr.bin/perl with
the extracted tar.gz.

Lots of good changes this time:
https://metacpan.org/pod/distribution/perl/pod/perl5320delta.pod

* a new "isa" operator
* A new feature "no indirect" that disables indirect object notation
* Unicode 13.0
* Chained comparisons ( $x < $y <= $z )
* IO::Compress now comes with the streamzip utility.

and a bunch of other unicode and regex things as well as new versions
of many modules.

It also includes the recent PERL_HASH fix for 64bit strict alignment
architectures and removes several local patches that were merged
upstream.

There are also several files that can now be removed:
