It is good to see functional languages in use for major industrial projects. From this book, it appears that Star is so used.
The book itself tries to cover a lot of ground, beginning with the merits of functional languages and continuing as far as concurrency, speech acts, and applications of advanced algebra and logic.
A reader should understand that this book is not intended as an introduction to functional languages and programming. Anyone seeking such an introduction would probably do better to study a more mature general purpose language such as Haskell.
