The Object contents are passed by ref, just like the enum contents are.

The difference is that the ref is implicit for the object. In other words, a
ref to a C object is implicitly passable as a ref to a base Object. A ref to a
C object *reference* is not passable as a ref to a base Object reference for
correct reasons.

The equivalent to your code for enums would be:

void foo (int *o) {
  o = new int;
}

enum E : int;

void main () {
  E *c = new E;
  auto n = c;
  foo(c);
  assert(c == n); // assertion passed
}
