}

OnionObject is the main type for all objects in the Onion VM. The VM’s types are all immutable(Mut is a immutable pointer to a VM object) If we need to mutate an object, it is IMPOSSIBLE to mutate the object itself, we can only let the Mut object point to a reconstructed object. reconstruct_container is used to reconstruct the container object, which is used to regenerate all Arc references to the object.
