Hi Will
> Is there more explanation of the puzzles in the book than on the website?
Yes, one of the main goals for us in writing the book was to provide more detailed explanations than are available on the site, and also to discuss alternative approaches and possible best practices for avoiding the puzzling behaviour. See
Nermin's comment in a different thread for a link to a sample chapter that should help demonstrate the difference.
Having said that, you'll probably get the most out of Puzzlers if you already have a reasonable degree of proficiency in Scala. The main aim of a puzzler is to highlight an example of the language behaving in an unexpected or counter-intuitive way. Having a reasonably clear expectation/intuition of how you think the language
should behave is pretty much a prerequisite for that. If you're just learning the language, that expectation/intuition is something you're probably still developing.
We
definitely don't want to make readers' heads hurt! Puzzlers should be fun and challenge your understanding of the language, not make you feel like you're sitting an exam. If that's how you're feeling right now, I'd suggest perhaps revisiting Puzzlers in a couple of months, when you feel you're reasonably proficient in Scala and want to "test your skill" ;-)
