On reflection, I have to say that I like this solution best. It is very
similar in flavor to
maybeNilObject?.someMethod()
I might even argue that it should only be used for Void return types, just
like that method call becomes essentially void if the object is nil.

}If any of the capture list evaluates to nil, the block is not executed. If
the block signature has an optional return value, nil is returned. Anything
else, you’re on your own.
