Personally I'd say if you're using anything older than 5.10.1, then you're a lost cause.

Some major new features were added in 5.10, including state, given/when, smart match and the defined-or operator. (Not to forget say, which although not major, is nice.) There were also important but less visible internal changes, such as to the regular expression engine. And there were some pretty big changes in the supposedly minor upgrade 5.10.1, including improvements to smart match, a Unicode upgrade, and autodie and parent becoming part of core.

Releases since 5.10 have had new features too, but these seem less compelling. Although I currently use 5.16, I have so far eschewed relying on post-5.10 features in publicly distributed code, preferring to keep compatibility with 5.10.

With regard to RHEL, it is well-known for shipping pretty ancient releases of software. Luckily, App::perlbrew will happily run on Perl 5.8.

PS: If the legal department object to installing a newer version of Perl via perlbrew, then it seems they would be unlikely to be thrilled about you downloading and executing random code from the monastery at all.
