I noticed on the OCaml mailing list that Practical OCaml is due to be released in the US quite soon. Could this be the first real competition that Jon Harrop will face for his excellent but pricey Objective Caml for Scientists ?!
Things are heating up on the OCaml book front at last, and Jon has been getting some rave reviews of his book! We have a long-running joke about how much I hate the colour syntax highlighting he used in his book, and it amused me greatly to note that someone else in the comments for the rave review of his book also shared my heretical opinion, ha ha!
