This system has v5.22.1. I don't know exactly how this perl was
configured. I didn't see the warning on other systems. Strangely, I
don't remember seeing it yesterday on this system, either. I might
try to reproduce the warning on another system and let you know. The
warning and this fix seem to be in line with the perl documentation,
though.

perl --version

This is perl 5, version 22, subversion 1 (v5.22.1) built for
x86_64-linux-thread-multi
(with 15 registered patches, see perl -V for more detail)

cat /etc/fedora-release
Fedora release 23 (Twenty Three)
