 As [comment:ticket:49940:2 mf2k has recently mentioned], as we come to the
 end of the year, its probably a good time to change the default perl from
 perl5.16 to perl5.22.

 Tasks to accomplish:

   * change the default variant of port perl5 to +perl5_22
   * change the hardcoded fallback perl branch in the perl5 port group from
 5.16 to 5.22
   * update any ports that declare perl variants to use the perl5 port
 group without forcibly declaring the default variant.  This will allow
 these ports' default variant to automatically follow that defined by the
 perl5 port group, simplifying future updates.  At this point, I believe
 there are only two ports that need attention.

 I realize that there are currently many ports left that depend explicitly
 on perl versions other than perl5.22 (#48365) but I don't see that as a
 gating task for executing this ticket.  Of course, they will have to be
 updated before any further outdated perls can be removed and perhaps
 changing the default will provide an incentive to finish these updates.

 Let me know if you have any comments or suggestions reguarding this
 proposal.  Otherwise, I will go ahead and make the changes in the next few
 days. I've already made the changes in my local port repo and they appear
 to work well.

 Ports that currently set the default perl variant forcibly (other than
 perl5) and don't use the perl5 port group:

   * biblatex-biber (dports, openmaintainer)
   * percona-toolkit (pixilla, openmaintainer)
