Subject: [PATCH] Fixes #1641 There's no need to explicitly raise StopIteration
 as that's what a bare return statement does for a generator function - so yes
 they're the same. As of late 2014 return is correct and raise StopIteration
 for ending a generator is on a depreciation schedule. See PEP 479 for full
 details. https://stackoverflow.com/q/14183803/248296
