I did some Prolog in college and always thought it was neat. I was able to internalize and reapply the idea of data and relation to make smaller rules engine type things in other apps. You see some similar patterns in some of the declarative build languages and here and there. I don't feel like I fully groc Prolog though. For example, how do you write fast Prolog? Often its fast but if its not, I feel a bit helpless. Are there any good articles with a bigger's look at Prolog performce?
