It's nice to see another book focusing on making FP techniques more palatable to a wider audience! Manning certainly seems to have been a tear with this topic lately, which is a good thing as far as I'm concerned.
Your book focuses on statically typed FP techniques -- comparing
Java and Scala -- but we've also recently had Grokking Simplicity, which aims to teach FP using JavaScript as an example language and therefore dynamically typed, and Data Oriented Programming, which uses Java as the example language but focuses on "pure data" using generic data structures and mostly avoiding the static type system.
Could you comment on what you see as the pros and cons of static typing in the context of FP, as a way to compare and contrast your book's approach to those other two?
In particular, how do you feel about
Alan Perlis' quote "It is better to have 100 functions operate on one data structure than to have 10 functions operate on 10 data structures." which many people feel argues more for generic functions on generic data structures?
