Uh, thanks for the help, Remi and Stefan. I could actually implement what I wanted using your tips. So, in my library, I can serialize any class given a "description" of it. Something like this: class A { int m1; char *m2; } typedef make_traits<A, int, CString
//A is now serializable. The CString class //is a modifier to treat the second field //as a c string A x A y stream << pack(x) stream >> unpack(y) //Now x is equal to y class B { unsigned int m1; A *m2; } typedef make_traits<B, unsigned int, NewPtr<A>
//B is now serializable. The NewPtr modifier //says that the m2 should be treated as a C++ class //pointer This is rather cool and impressive. Using your tips I could go further, so it was not needed anymore to specify the members in the correct order, nor all of them. But in the end I found it quite ugly. So I decided to go through a another way, easier for the user and with a cleaner syntax, but not so "hardcore". But your ideas are great, and probably have a good use. So, thanks for the help.
