May in the code you posted you don't. May be you don't change it in the whole project. But if you do, it breaks too many Python assumptions. > Also I have no option to change the class hierarchy.

Also, Boost.Python has built-in functionality to convert Python string and std::basic_string. I don't know what effect class_< std::string > registration will have. -- Roman Yakovenko C++ Python language binding http://www.language-binding.net/ _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
