From perldoc perlsub:
Signatures
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.
