This sounds fun until your entire stack is on Perl in 2023 (which, is fine-ish when your CTO was the perl project lead). But then you have a bajillion dependencies that aren't really updated anymore, you end up owning most of the Mail::Toolkit libraries, etc. and nobody really knows perl that well. I mean, a lot of us can jimmy around in Perl, but of the real Perl Gurus in the world, you will end up hiring 50% just to keep your company going
