I agree there are rough edges, and for specialized use cases like yours, you might have to walk that extra mile. But when I hear that a framework/library/tool is worth nothing just because it is written in C++ and not in the hip Ruby/Python/Go, it makes me sick. This guy wrote CppCMS taking inspiration from modern frameworks hoping to make life better for himself and for people who care to write webservices/apps in idiomatic C++ and NOT C. Imagine if someone had written a had a well designed, idiomatic C++/Lua API(like, say, boost::python) and open sourced it, would we not have commended their efforts?
