Nope, it does not - you'll either have to declare a new serialize() 
function or get it from the base class.

eg

struct A {
   template<typename Archive>
   void serialize(Archive&, const unsigned int) { }
};

struct B : public A {
   using A::serialize;
};

PS no offense, but my name is spelled with a capital 'I' not an 'L' :)
