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?
