 // The default vector deserializer does resize and then we deserialize into
 // those allocated slots. However, the implementation of vector (at least in
 // GCC's implementation), creates a new empty object using the default
 // constructor, and then sets the rest of the items to that empty one using the
 // copy constructor.

 // transfer the inner class when you do operator=, the entire vector will end
 // up referring to the same inner class. Deserializing into this will just end
 // up overwriting the same item over and over, since all the SerializedVars
 // will refer to the same thing.
 //
 // The solution is to make a new object for each deserialized item, and then
 // add it to the vector one at a time.
