Thanks Ben! When testing, I found that a type checker regression from 7.10
to 8.0 that I thought/hoped was resolved is in fact still present in this
release candidate. I filed a new bug:
It originally seemed the same as #12175. But unfortunately, although that
problem is resolved in 8.0.2-rc1, this one is still around (though they may
still be related).
