Applying PyObject_RichCompareBool to two `nan`s can be true if the two nans are same object, i.e. ``` a = float("nan") PyObject_RichCompareBool(a, a, Py_EQ) // True ``` I read the document (https://docs.python.org/3/c-api/object.html?highlight=pyobject_richcomparebool#c.PyObject_RichCompareBool) and understood it is intended, but there should be gentle comment to tell users this behaviour.
