Unfortunately, I'm not certain why you get that behavior. I think we'd have to
get into a debugger and really dig around to find out. I would have expected
all three uses of `F` there to make `*out` ptr non-null. The only distinction I
can think of is that the odd-man-out is a discarded value expression. But why
that should matter for typo correction is a mystery to me currently.
