I'm not sure why but Prolog seems to have more misinformation circulated about it than any other programming language I've ever seen. I'd take a lot of the information in these comments with a grain of salt. If anyone is interested in authoritative and accurate modern information about the language, please see Power of Prolog[1][2].
