Summary: Down to earth pattern exposition
Review: While this is one of the smaller books on my shelf, its proportionate value is very big. Vlissides does a lot of tying together of the work presented by the GoF. Chapters 2 and 3 give excellent concrete examples of how to attack a design with patterns (ch. 2) and how to deal with some of the issues that come about with various patterns (ch. 3). While I do not work with code generation tools, I can appreciate the usefulness of the Generation Gap pattern for those situations.The other three chapters (1, 4, and 5) pull back the curtain a little bit on how Vlissides (and the rest of the GoF) approach patterns. You will gain new insights and a better appreciation of for the material. The dialogue between the members of the GoF on Multicast/Observer/Typed Message shows that these folks really are as mortal as the rest of us and have candid debates. Pattern Hatching is enjoyable to read, and it will begin to take your understanding of patterns to the next level.
