The instructions for the C interface to the Python set class

  http://docs.python.org/c-api/set.html

say to use PyObject_GetIter and follow the iterator protocol. After
following the instructions for the iterator protocol here,

  http://docs.python.org/c-api/iter.html

I was able to successfully iterate through a set object. However,
PyIter_Check(obj) returns false yet set objects follow the iterator
protocol. Is this the correct behavior?

Thank you.

Kind regards,
