Prolog is the only language that I've ever learned that feels like magic. Of course, it's not, but it feels like that. I'm still learning it, but I feel it and the logic paradigm are underused. I wonder if it's fair to consider it constraint-based programming rather than just logic programming. I used the book Thinking as Computation to learn it (and still am), and that's what it felt like we were doing in the book: just setting up constraints for the program to run through and find matches for the constraints.
