>Does the course cover Functors, Applicatives, Monoids, and Monads? What about other higher-level functional constructs (Arrows, Zippers...)?

Nope. It's very intro level, though the students basically begged Odersky for a part II, and he seemed very open to it.

And I totally didn't mean to imply that I thought people should learn Scala instead of Haskell. I was just sharing a FP resource I found helpful.

Not actually having mastered the higher level functional constructs yet myself, I really don't have a firm opinion about which is the "better" approach. Personally, I've looked at both languages and I know that each helped me understand the other. So if I have any opinion, it's that if you get stuck, it's probably a good idea to approach it from another angle, like the author is doing.
