I have 20 year old Perl code I run in production. I had to re-install it our move to Amazon Linux 2. My 10 year old install process for the cpanm setup still worked. My 10 year old Python had to be moved to python 3; but the 20 year old Perl still runs
I’m a big time python fan (80% of the code I write is python) but growing up I loved Perl (after starting out as a PHP dev) as a scripting language and I hate how much flak people give it. Though I do understand since there’s a million ways to do everything in Perl if you aren’t familiar with the language it can look daunting. But I’d argue the same can be said about JavaScript and I still love that language as well.
