Overloading embedded Python functions using PyArg_ParseTuple.

Question

If I'm trying to overload an embedded Python function so that the second argument can be a long or an Object, is there a standard way to do it? Is this it?

What I'm trying now (names changed to protect the innocent):

  bool UseLongVar2 = true;
  if (!PyArg_ParseTuple(args, "ll:foo", &LongVar1, &LongVar2))
  {
      PyErr_Clear();
      if (!PyArg_ParseTuple(args, "lO&:foo", &LongVar1, convertObject, &Object))
      {
         UseLongVar2 = false;
         return NULL;
      }
  }

What I normally do is have two C functions that take the different arguments. The "python-facing" function's job is to parse out the arguments, call the appropriate C function, and build the return value if any.

This is pretty common when, for example, you want to allow both byte and Unicode strings.
