Discussion on: Why use pointers at all.

I've done so several times.

Here is the simplest requirement, again.

When passing by reference, modifying the parameter modifies the argument.

void foo(int &a) {
  a = 2;

int main() {
  int i = 1;
  cout << i << endl;
  // Outputs 2.

Under that definition, no passing by oranges does not have the same semantics as pass by reference.

This however changes the subject to the parameters of the functions. I have been talking about the object for which the parameter refers. Could we stick with talking about the concept I'm actually trying to get across rather than introducing a introducing a different one.

Since pass by oranges is not a term used in the Java spec, could you describe the pass by oranges semantics using spec terms?
