OK, so now I do:

PyRun_SimpleString("interact('---Starting Python---', input)\n");

where my input function looks like:

static PyObject * input(PyObject *self, PyObject *args)
{
	char *string;
	if (!PyArg_ParseTuple(args, "s", &string))
		return 0;
	gld::gMsgView()->printf(MSG_NONE, "%s", string);
	return PyString_FromString("");
}

(I'm returning an empty string just to test the above). This goes
into an infinite loop - I'd have expected it to output the prompt
'>>>' once, then wait for a non-null string.

Any ideas what's wroong? I've looked at the implementation of
builtin_raw_input() and can't find any clues to help.
