Stuff with the Perl Foundation. A couple of patches in the Perl core. A few CPAN modules. That about sums it up.
For anyone who's interested, the next issue of The Perl Review will have an article entitled "Logic Programming in Perl." This will be a greatly expanded version of my OSCON talk on logic programming.
In this article, there will be a basic introduction to Prolog, via AI::Prolog. I will also be discussing its strengths and weaknesses vis a vis Perl and relational databases.
For those interested in the topic, it's also worth looking at Logic, a rather interesting take on logic programming by Luke Palmer. For much better performance, there's also Language::Prolog::Yaswi by Salvador Fandiño García. The latter allows you to access SWI-Prolog from Perl.
It's a nice article :) (Score:2)
The first people who will get to see it will be the YAPC::EU attendees. Just a couple of minutes ago I delivered the final product to Alberto who is going to print up a bunch in Portugal thanks to Outcome Technologies [outcometechnologies.com], one of the big sponsors of YAPC::EU.
I'll be talking more about the issue in a couple of days, but now I'm dead tired. I've been working on it almost non-stop for the past two days (well, I did go out with Josh, but nothing else I swear!). Alberto is quite the task
