Stefan has recently been trying to get compile-time constants from sizeof() into the parser. As he knows, this is going to mean handling such things as template instantiation and overload resolution. This is a great opportunity to learn more about how C++ works and to create a compiler platform that's actually usable by C++ programmers for prototyping new features -- one of the major obstacles in C++ standardization is that the source for the only open-source C++ compiler has a steep learning curve.
I should mention that the design of the C++ parser allows to manipulate the generated parse tree in-memory and write it out into a file again in a non-lossy way, i.e. it could indeed be used as a source-to-source compiler. Regards, Stefan
