- * Yield `ref`'s value while setting `ref` to NULL.
- *
- * This can be used to give a strong reference to a callee:
- *
- *   add_foo_to_list(list, BT_MOVE_REF(foo));
- *
- * or in a simple assignment:
- *
- *   my_struct->foo = BT_MOVE_REF(foo);

- * When moving a reference in a function call, the reference is given to the
- * callee even if that function call fails, so make sure the called function
- * is written accordingly.
