reachableroots: fix transposition of set and list types in PyArg_ParseTuple This is being masked by the function not properly returning NULL when it raises an exception, so the client code was just falling back to the native codepath when it got None back. A future change removes all reason for this C function to return None, which exposed this problem during development.
