If you re like me, you re excited by what people do with template metaprogramming (TMP) but are frustrated at the lack of clear guidance and powerful tools. Well, this is the book we ve been waiting for. With help from the excellent Boost Metaprogramming Library, David and Aleksey take TMP from the laboratory to the workplace with readable prose and practical examples, showing that "compile-time STL" is as able as its runtime counterpart. Serving as a tutorial as well as a handbook for experts, this is the book on C++ template metaprogramming."Chuck Allison, Editor, The C++ Source
