So, you are saying that Perl is used in a big bank? Even now? That is good!!

I've heard very scary stories about IT in banks. Lots of legacy software (COBOL and the like) dating back to 1960s or 1970s, emulators in emulators, and a lot of pre- and post-processing around that to keep things working. "Never change a running system" codified in expensive and time-consuming recertification processes.

Don't expect better from other businesses. I know of medical lab equipment running in production environment way into the 2000s based on a CP/M system. And even worse, a MUMPS system running the main business, both medical and financial, hacked togeter since the 1980s by a few unskilled people, in the same company, also way into the 2000s.

You will find Perl in a lot of unexpected places over time. It's called swiss army chainsaw for a reason. I've used Perl in all of my jobs over the last two decades, and I will continue to do so. It does not solve all problems, but it solves a lot of small problems with very little effort, and the bigger ones with reasonable effort.
