Describe your changes
This change prevents a force-casting crash when fetching a wrapped value with mismatched types.
nil
is returned instead. A mismatched type can be caused by a redefinition of a key or data corruption. The change allows Foil intergrators to handle thenil
case rather than crashing. This change does not impact the public interface and adds a unit test to verify mismatched types are handled.
