Hi,
h3. *The Problem:*

Currently, if I try to serialize and it can't be serialized by the default serialization context I get 
SerializationCallbackError. So the problem is that I have to try to serialize the object in order to know if it is serializable by the package. That can be a very expensive operation for a simple check if the object contains a large amount of data.
 
h3. *The* *Requested*  *Improvement / Feature**:*
 
A function that checks if the type of the object I'm about to serialize is serializable by the package (meaning it is registered under the type_to_type_id dictionary).
