    Handle StopIteration for Py3.7 PEP 0479
    
    Replace raise of StopIteration with return.
    
    PEP 0479, https://www.python.org/dev/peps/pep-0479/, makes the
    following change: "when StopIteration is raised inside a generator,
    it is replaced it with RuntimeError".
    And states: "If raise StopIteration occurs directly in a generator,
    simply replace it with return."

  replaced with RuntimeError, resulting in:

  RuntimeError: generator raised StopIteration
