R1708 (stop-iteration-return)
Problematic code:
def foo(n): for i, num in enumerate(range(n)): yield i, num raise StopIteration 
Correct code:
def foo(n): for i, num in enumerate(range(n)): yield i, num return Rationale:
According to PEP479, the raise of StopIteration to end the loop of a generator may lead to hard to find bugs. This PEP specify that raise StopIteration has to be replaced by a simple return statement.
