Perhaps the final version of the book is different, but I would never
recommend the book I saw.
I skipped all that stuff and just read the chapters on functional
programming. There was good stuff on lambda and map. I don't know
about the rest of the book one way or the other.
It is minutiae. When you use Latin nouns in English everything gets
turned into the normative case. Otherwise people would go nutty in the
head.
