I'd probably end up rewriting it as 50 lines of code that used a bunch of pure perl libraries and then use https://p3rl.org/App::FatPacker to bolt the dependencies onto the front for distribution so it was still a single file to install for everybody else.

(there's a lot of perl out there that uses techniques I would switch away from as soon as I got past a one liner in the middle of a pipeline, alas, but it doesn't have to be that way, perl just doesn't stop you blowing both feet off ;)
