Basically he wanted home automation in Perl to control his geothermal/solar house, and ended up reimplementing Perl with AI. That's some yak shaving...
There are plenty of other interesting features like auto-FFI, bytecode caching (similar to Python's .pyc files), and "daemonize" mode (similar to mod_perl or FastCGI).
In case HN shows its user hostility again by cutting off the URI fragment, the intended deep-link was presentation slide #/4/1/1
I can't help but giggle at the fact that AI written project doesn't seem to get its home page right.
I had to build a Perl implementation of the Chaskey mac algorithm. ChatGPT spat out a working Perl prototype based on a C file for Arduino. It quite slow with not very much to optimize, so I made it write it with XS. A hour later I have a working XS implementation that compiles and tests cleanly.
So the AutoFFI thing is super interesting. The .plc also.
