> 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).
