Is the iter() really needed? Couldn't the contract of
__await__ be that it always returns an iterator?
I wrote it the wrong way. iter() isn't needed, you're right.
This is a quote from the ref implementation:
if (!PyIter_Check(await_obj)) {
PyErr_Format(PyExc_TypeError,
"__await__ must return an iterator, %.100s",
Py_TYPE(await_obj)->tp_name);
