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?
