Any other concerns? I think I've elaborated on why the ignore/exclude alternative is not better.

Otherwise, eventually, it would be great to be able to understand the various macros and how they could serve as checks for later accesses, but I think this is an improvement on the status quo (we've seen lots of such googletest false positives).

Thanks!
