What values will be in array after Restoring, if before Saving they were [1, 2, 3], after saving changed to [5, 6, 7]?

In case that wasn't clear, the simple values in a composite object are not separate items, but are part of the composite object. Bear in mind that [5 6 7] is a new composite object, you'd have to use put or putinterval to update the elements of an existing object.

The restore puts back all non-global composite objects to their contents before the matching save.  The magic by which this happens is implementation dependent, but one way to think of it is that all non-global composite objects are saved in a container on the save, and put back on the restore. (This is not how it works, but what seems to happen).
