This is wrong and ignorant in several ways. It really hurts.

Sorry that it hurts, but any guideline or policy in this area will step on *somebody's* toes. And this guideline wasn't chosen out of ignorance.

If we want to silence these diagnostics we can either complicate the source code or complicate the debugging tool. In cases like these I'd rather complicate the debugging tool, as that is easier to maintain than adding complexity to all the source-code programs that the tool is applied to. Besides, debugging tools come and go, but source code lasts forever.
