Hmm,
storing (and then restoring) weak containers as they are , i don't see
anything special which must be done there.

The special logic how to deal with weak containers are still remains
same, as long as you correctly restoring the object,
and as long as this logic is correctly written. So, i cannot see what
Fuel needs to do special with weak containers.

You may need to deal with storing instances of WeakRegistry, since it
registers itself into WeakDependents array,
which is scanned for finalization. So, you have to make sure that if
WeakRegistry instance was registered in weak-dependents
array, then you should also register it when restoring it back. (and
if it was not registered - then of course not register).

But WeakRegistry is a regular object (not a weak container by itself,
and only indirectly it using
weak containers by delegation).
