auto is called a storage class, but where did you read that auto would 
make the variable stop existing at the end of the scope ?

int delegate(int) add(int i, int j)
{
  auto k = i+j;
  return a => a+k;
}

Are you sure k will stop existing at the end of the scope ? I have no 
compiler at hand to check this, but I would be very surprised.

Object Create()
{
  auto k = new Object();
  return k;
}

Same question.
