Which version of perl do you use (or are you forced to use) and why?
I maintain the perlfaq, and today I finally updated the answer to "Which version of Perl should I use?" The old answer focussed on the transition from perl4 to perl5, with touch-up updates to reflect the current version of perl.
I completely rewrote the answer to basically say "Well, it depends..." It's not a "live" answer because I've only proposed the change to perlfaq-workers several minutes ago.
This got me to thinking though: which versions of perl are people really using, and why are they using them? I'm not talking about which operating system they are using, but which release. I know that a lot of people and places are using a lot of different versions, and some for very good reasons. I think I covered those in the new answer.
Even though Perlmonks is a self-selected sample, and I expect most regulars are using perl5.8.x, I still wonder what the shape of the world is, and if the new answer is both useful and realistic (random version bashing from one man perl shops isn't very helpful to large organizations, for instance).
Which version of Perl should I use?
There is often a matter of opinion and taste, and there isn't any one answer that fits anyone. In general, you want to use either the current stable release, or the stable release immediately prior to that one. Currently, those are perl5.8.x and perl5.6.x, respectively.
Beyond that, you have to consider several things and decide which is best for you.
