I come from an FP background, and this book was interesting to me as the author very clearly has a very different (imperative, systems) background. In some cases we have very different opinions, in some cases I'm completely agreed (e.g. "define errors out of existence" is extremely common in FP, usually under the term "make illegal states unrepresentable"), and in other cases I feel they were half-way to FP but couldn't quite get all the way there (e.g. the editor example is a classic interpreter, but they didn't make the connection IIRC.) I only skimmed the book and would like to go back for a more detailed review. Curious if anyone else with an FP background had the same or different experience.
