That's really nice. I never really got into perl but i was moved by some sysadmin friends back in the days playing crazy tricks right in front of my eyes... doing the same in bash would have taken me minutes or even hours, so i always felt like this was some kind of great wizardry.

But perl is not really the most user-friendly language to learn in my opinion. I think raku is much better in this regard, but unfortunately is not deployed widely (yet?).
