Would you elaborate on why you want to ignore exceptions here?

Note that this file is now gone.

But in all the other callers, the reason is that this serialization should be as
invisible as possible to script. The whole patch is an attempt to simulate old
behavior (where the detail/state/data properties were directly accessible from
different worlds), and anything that makes the copying noticeable (beyond the
necessities, like calling getters on the object to-be-copied) should be avoided.

None of this behavior is specced; it's all an attempt to make extensions behave
sanely.
