> i have stuff literally written a deacade+ ago, still working without issues Maybe this works if you run your Perl in the exact same environment the whole time, or if you're writing stuff on a very small scale and don't need to use many CPAN modules. But for large applications, you'll be using CPAN modules heavily. And you'll need to run your Perl in new environments - if for no other reason, because you'll need to move to new operating system versions to pick up security updates. That's where the problems start. If you're using a reasonable number of CPAN modules, this inevitably breaks some of them. And because the Perl ecosystem is essentially dead, those third-party modules are usually abandoned.
