Does a simple void cast work? E.g.:

I haven't found the magic using that approach.

That's too bad; so you need to fix it the "hard way" after all.
It seems like a compiler bug to warn in that case. Presumably the intent
of the warning is to let you know that you're *unintentionally* ignoring
a result. The void cast makes it clear that it's intentional.
