[Python-Dev] PyList_Insert() et al.

[David Abrahams]

Check it out:

int
PyList_Insert(PyObject *op, int where, PyObject *newitem)
{
 if (!PyList_Check(op)) {
  PyErr_BadInternalCall();
  return -1;
 }
 return ins1((PyListObject *)op, where, newitem);
}

Since the implementation of ins1 gives the subclasses' re-implementation of
insert() no chance to execute, shouldn't this check be changed to
PyList_CheckExact?

If not, what needs to be added to the documentation to make it clear that
these functions really do subclass slicing?
