Object-oriented preprocessor fit for C++

C++ retains the ANSI C preprocessor, although its limitations have been widely recognised. The authors describe FOG, a meta-compiler for a super-set of C++, that provides replacement preprocessing and introduces static meta-programming, while preserving the spirit of C++. They show how implementation of preprocessor functionality in an object-oriented style eliminates unnecessary replication from practical C++ programs, and supports recent object-oriented programming developments to a much greater extent than existing tools
