Hi, I'm aware that deleting a scalar from subpatch automatically invalidates all pointers to scalars residing in this subpatch (as an easy way to prevent stale pointers).
Is it desired behaviour that deleting an object also invalidates all pointers? Usually, deleting elements from a linked list shouldn't invalidate iterators to remaining elements. and since the deleted element is an object, there is no way a [pointer] could have pointed to it, so there's no need for preventing stale pointers...

Furthermore, creating an object (e.g [+]) will also invalidate all pointers. I wonder why?
