You're not seriously still running your code without warnings enabled, are you? While simultaneously trying, based on your last few questions, to increase your test coverage numbers?!
This is precisely the sort of "technically correct" yet unnecessarily abrasive comment that drives people away from communities. You're a smart person; surely you can find more constructive ways to offer feedback than getting all hot and bothered because someone is making a few mistakes along road of learning a new skill (not to mention giving this community a continuing reason to exist!) I'm asking you, gently, and as a fellow member of this community, to please do better.
