--- Comment #47 from rusty at rustcorp dot com.au --- Civility please. We're all trying to find a path to improve things here. But accept that the conversation on this issue is only a weak indication of consensus. As Andrew Pinski says "people are mis-using this attribute", and Jakub Jelinek makes a similar point. The use of _wur has changed from "ignoring the result is criminally wrong" to "possibly wrong". I still put a comment complaining about this every time I hit it, which is about once or twice a year. But I have little more to say; it's been almost 20 year after all :)
