But I bet the warning we're getting there is complaining about exactly
that thing. It's possible that it means "warning: i've optimized away
your unused function into nothing" but I think it's more likely that
it means "warning: i just emitted dead code". Indeed, I suspect that
this is why that test is written that way in the first place.
