+Subject: [PATCH] Don't raise StopIteration in generators, no longer allowed
+ with Python 3.7. Fixes #3622
+
+Raising StopIteration from a generator has been deprecated with Python 3.5 and is now
+an error with Python 3.7: https://docs.python.org/3.8/library/exceptions.html#StopIteration
+
+Just use return instead.
