Did I mention Perl is old and shit, and a complete mess? Are you really sure you want to use a Perl app?
Try libio-aio-perl
There are so few apps out there for what I want, that are free and self hosted, that I don't really have a huge choice. Plus it's only a bit of fun, nothing serious,
Tried your suggestions:
