That makes Perl 5.10 “the future” from my perspective.

Living in the past seldwhen is a good idea.

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?

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.
