If we're going with the instance check, I'd probably stick with
Jellyable and not Copyable (since you might have a referenceable or
viewable exception object) - that matches the actual jelly()
I'm still wondering if just trying to jelly the object isn't the
best approach in the end though, since checking the instance class
excludes the cases where the security options permits the object
to be sent (e.g., I might use the security options to let standard
Python exceptions through without having my own Copyable subclasses).

Close - option 1 (Jellyable subclass) is one half of the jellying
process - the other half is the type being allowed by the security options
and being supported by the default jelly handling of native Python types.
