Thanks! Thats exactly what I was aiming for. I'm glad that came across. I was thinking the same thing although I didn't actually discover https://learnxinyminutes.com/docs/perl/ until after I had written Minimum Viable Perl.
Yes, there are several legacy systems where a full rewrite is way more risky than maintenance-and-minor-enhancements-only. If you're surprised that Perl is still alive, don't go asking about how many COBOL systems are still out there!
