CC is a good book that's not steeped in programming terminology and is easy for even laypeople to understand. However it would've been nice for Steve to incorporate some code snippets from a functional language, just to compare and contrast how things are handled differently between paradigms.
I agree with the missing parts of the book (btw: anyone interested in that might find "Programming Language Pragmatics" by Michael Scott interesting), however, I think that there is not enough experience on using functional programming languages in an industrial/professional setting.
