What do you think of this control block?

Stick to standard C:

  1: Initialize a pointer variable to `NULL`
  2: Allocate memory for the pointer (this might fail)
  3: Correctly free the pointer memory, regardless of allocation
     success/failure

Specifically:

    PyObject * obj = NULL; /* step 1 */
    do /*once*/
      {
        ... possible other stuff ...
        allocate obj; /* step 2 */
        if (PyErr_Occurred())
            break;
        ... possible other stuff using obj ...
      /* all done */
        result = tempresult;
        tempresult = NULL; /* so I don’t dispose of it yet */
      }
    while (false);
    Py_XDECREF(obj); /* step 3 */
