poulhs has asked for the wisdom of the Perl Monks concerning the following question:

We (as so many others) use perl intensivly, but we are currently stuck with the stock RHEL6 perl (that is 5.10.1).

I am considering building our own perl (in /opt/somehwere), adding the modules that we need, and keeping that up-to-date (using jenkins to build our own RPMs for deployment). I have a feeling about the amount of work involved with this (been down that road before), and my boss asked the ultimative question:

Is it worth it?

So I started to prepare a what's-the-difference tutorial (from perldelta's), then 5.18.0 came along and threw given/when and ~~ into experimental::smartmatch, so now I am (almost) back to square 0. Almost all I got is some optimizations and some hash-key security...

Compared to 5.10.1, why should I upgrade to 5.18.0?

Thank you Monks, for allowing a humble perler interrupt you.
