New lessons in two courses!

This week, we’ve added content to two of our courses, Functortown and Validation. The Functortown lesson is called Zippy applicatives and discusses the two list applicatives: the normal one, and ZipList. Second, as many of our subscribers are aware, we had turned the Validation course into a book, and we made that free to anyone who was subscribed to Type Classes at the time when we published the book. The book included two chapters that did not appear on the site, however. The first of those, now added to the course, is on Coercible. We expect to add the final chapter next week, so all that content will be available to all our subscribers. Enjoy!
