"At some point Perl 5.22 or one of its successors will make it into Red Hat Enterprise Linux. And at that point we have a problem."
This made me laugh this morning, version 5.22 will probably be included in the 8.0 release? So we have a few years to go. RedHat 6.* is still running Perl 5.10 so no worries about anything breaking in the next 5> years.
