Ok. I'll just push the equals change today then.

If it helps, I ran all the tests. There weren't any more failures
than usual. There were fewer actually. I run all my tests on a debug build.
On a regular build, there are only 4 failures (which are expected), but
before any of today's patches, I got 20+ errors on my debug build. With
today's patches, I get ~12.

Denis.
