Subject: [PATCH] Avoid raising StopIterator in generators. (#5263)

According to [PEP-479](https://www.python.org/dev/peps/pep-0479/) StopIteration should not be used any more to indicate the termination of a generator.
Starting from Python 3.7 this behaviour is always enforced and a RuntimeError is raised instead.
Instead of raising a StopIterator exception, we now never execute our yield statement.
Since it is present Gen is still a generator but it will never yield any value.
