[Boost-users] [Boost.Python] Is it possible classes X Y returned each other?

Hi, all! I'm writing python module and run into obstacle. I need a couple of classes which can return instance of each other. This is part of my module: /// mysupermodule.cpp ... struct X { X():s("default") {} X(std::string s):s(s) {} Y getY() const { return Y(); } }; struct Y { Y():s("default") {} Y(std::string s):s(s) {} X getX() const { return X(); } }; ... /// And I got obvious error: mysupermodule.cpp:45:5: error: ‘Y’ does not name a type. How can I solve this task? Regards Sergiy
