​From perldoc perlsub:

    WARNING: Subroutine signatures are experimental. The feature may be
    modified or removed in future versions of Perl.
​And according to perldelta the signature syntax did change between 5.20
and 5.24.  This is bleeding edge.  My perl code is deployed on CentOS, but
I also test it on Fedora to ensure an upgrade path.  ​I think you should
have a talk with your developers or software vendor about the supported
deployment environment and path for perl and system upgrades.
