Since when is Perl 5.16 “ancient?” It’s only 4 years old.
CentOS 5 just left supported status, which shipped Perl 5.8.8 from first
release to last, which means I’ll probably still be limited to Perl 5.8
features for a few years yet, since the remaining CentOS 5 boxes I’m supporting
can’t be upgraded and won’t likely be turned off until they fall over dead.
That makes Perl 5.10 “the future” from my perspective.
Living in the past seldwhen is a good idea.
If this sort of stance seems risible to you, you probably shouldn’t be using
CentOS. This is what distinguishes a “stable” type of OS from a “bleeding
edge” one.
When a version of a software has been released 20 years ago,
that doesn´t mean it´s more stable than a version of that
software which is being released today.
Of course, you can consider "never change the version of the
software" as something making for a stable OS. But what about
the bug fixes?
At least the state feature is required.
According to the docs,[*] that feature has been in Perl since 5.10. This
appears to confirm it:
$ perl -e "use feature 'state'" && echo yes
Are you looking for something else, or do you have a simple test case that
shows what’s provided in CentOS 7 is insufficient?
Ah, yes, that does work. Sorry, I guess it was signatures rather
than state. I´m getting
Feature "signatures" is not supported by Perl 5.16.3 at ...
with CGI scripts. And who knows what else might cause problems.
The software has been written with perl 5.20.1, which is already
rather old.
