Here's an implementation of Neil's idea.

*** abstract.c 2001/10/01 17:10:18 2.83 --- abstract.c 2001/10/05 15:49:04

*** 1805,1810 **** --- 1805,1829 ---- else if (PyType_Check(cls)) { retval = PyObject_TypeCheck(inst, (PyTypeObject *)cls); }

• else if (PySequence_Check(cls)) {

•     int i, n;

•     cls = PySequence_Fast(

•         cls, "isinstance() arg 2 is an unacceptable sequence");

•     if (cls == NULL)

•         return -1;

•     n = PySequence_Size(cls);

•     if (n < 0)

•         retval = -1;

•     for (i = 0; i < n; i++) {

•         retval = PyObject_IsInstance(

•             inst, PySequence_Fast_GET_ITEM(cls, i));

•         if (retval != 0)

•             break;

•     }

•     Py_DECREF(cls);

•     return retval;

• }
  else if (!PyInstance_Check(inst)) {
      if (__class__ == NULL) {
          __class__ = PyString_FromString("__class__");
