If a book on programming promises examples in its title, I don't expect that the book doesn't explain the syntax of the language hardly or at all. It is true that the author shows programming examples, but I am not so sure if the book's claim to be a "developer's guide" is justified. I must admit, though, that the author explicitly aims at an audience of intermediate-level Small Talk programmers.
The most interesting parts from nowadays' perspective is the rather pure view on object-oriented programming. Usually an experienced software developer using the OOP paradigm doesn't think about control structures anymore. "if/else", "switch", "for"-and "while"-loops are all procedural? So what? The Smalltalk way of pure OO handling of such control structures has historically not borne too many fruits. But it is interesting to think about them.
