Thanks Stefan for you answer.
I think I got you on the wrong foot, I don't really suggest that what the C++11 have done is bad.
I am only introducing something that is different and I am interested to see where it goes.

When I wrote :
Stefan_Lang wrote:when an object is freed any other pointer to it get nullified


I know it is a quite an dangerous concept.
In my mind I have this idea, like a little snow ball, I want to roll it and see where it goes.


what are other parts of your application supposed to do when the pointer they rely on suddenly got nullified?

They are not in a worst state than calling an object that has been freed.
The . or -> operators can check if the pointer is null or not.

How can you guarantee that your whole application isn't left in an undefined state because an operation couldn't be completed?

I am not sure I follow your thoughts.
the free function would basically do:

free(memory)
{
  foreach pointer in the entire system who point to memory
     *pointer = null
  real free(memory);
}

If the pointers got reused later by the rest of the application it is bound to crash anyway as you're not supposed to use a block of memory that have been freed.
With this mechanism you can check very deterministically whether the block was freed by simply testing the pointer value.

Again I am not here to start a religious war, I am not even saying this is the way to go. I am merely asking what if?
