/// to the serialization scheme they want to support. For example, "Read"

/// sense for different types; a class need only implement one of them.
/// Serialization and deserialization of pointers are specially handled
/// by the Serializer and Deserializer using the EmitOwnedPtr, etc. methods.
/// To serialize the actual object referred to by a pointer, the class
/// of the object either must implement the methods called by the default
/// behavior of SerializeTrait, or specialize SerializeTrait. This latter
