I’m not ruling out the possibility of updating the book, but I also don’t have any real plans to do it right now. If there are ever concrete plans for a 1.0 version of the compiler, then I would definitely like to update the book and think about making print copies available.
That said, I think it’s great that the book is still being updated, so thank you for that! That was definitely part of the original intent of using a creative commons license on the material. So as long as the terms of the license are observed, I’m happy to see a version developed, on purescript-contrib or elsewhere.
