- The possibility to consider as a plain data member, any method (getter/setter ...) of a class, even if there is no underlying member, or if they are private, and also base classes.
OOPS. I didn't read the last two about dynamic sttributes and the "consider as plain data member". I don't have any idea how fusion could be adapted to handle these needs, especially since I'm unclear about what is the "consider as plain data member" need. Could you explain more or provide examples?
Please let me give you a silly example: struct Person { std::string _name ; int _age ; bool is_retired(void) const { return _age >= 65 ; }; }; When serializing such an object, many users would like to have 'IsRetired' saved like the other members. This may sound silly, but sometimes users are always right :):):) . So, CRD allows to have in a definition list, not only class members, but also methods of a given signature.
