The daynight mechanics in that game were a lot of fun . <| sep |> When you ' re being decomposed by the maggots in the ground and your consciousness has ceased to exist <| sep |> Yes . However , these days the truly useful Prolog implementations SWIProlog , YAP , SICSTUS , and very importantly Logtalk I apologize if I am missing any do have all the tools for programming in the large . This has nothing to say about the usefulness of Mercury , just pointing out that things have moved forward . As for efficiency for real , large applications , any of the Prologs I have listed above is good enough . The bottlenecks like sorting or string input and manipulations are taken care of by the implementation , about as efficiently as you could ever get . And you are left with a very highlevel and comfortable language for dealing with the business logic , which is where Prolog really starts to shine .
