Uh, that was one example of what it might be good for; I doubt that the
use-case has now vanished entirely. While I'm still dubious about the
reliability of suppressing error messages, if people have been using this
type of coding for nearly 10 years then it probably works well enough
... and more to the point, they won't thank us for arbitrarily removing
it.

I think we should leave established practice alone here. It might be
confusing at first glance, but that doesn't mean it's the wrong thing.
