That being said, I'm a professional dev and we own a decent amount of perl. That codebase is by far the most difficult to work in out of anything we own. New hires have trouble with it (nobody learns perl these days). Lots of it is next to unreadable.
I agree that like any other language, perl can be written well and can be written poorly. That being said, perl makes it _really_ easy to write something poorly, in contrast to something like python which is a bit more rigid and tries to have one right way to do things.
I still use perl pretty extensively for little one liners, but at this point we are actively trying to get rid of as much perl that we own as possible. We find that rarely writing anything longer than 10 lines should be done in perl, if only from a readability and maintainability standpoint.
I love perl. It was THE game changer for many many years. But perl is falling out of fashion quick.
I'd have no problem working in the language with some very rigid guidelines and a bunch of experts.
But the reality is that nobody is hiring perl experts, perl experts are becoming more and more scarce, and most new hires have a bit of experience with py or rb. I dont dislike perl, I'd just argue it's almost always the wrong thing tool for the job these days.
In a previous life I worked at a large E commerce company. You've likely ordered from them. Pretty much everything ran on perl/perl Mason for over a decade. At that time perl was the cool new thing that everyone wanted to pick up. Now (or when I left a few years back), most of that code represented a liability if it needed to be changed.
IMO this is just the cycle of a programming language.
I remember reading Spolsky articles where he talks about VB6 like it's some shiny new amazing scripting language, akin to python 10 or so years ago. But alas, time moves on and so do most programmers.
