Well, I can see why you'd think that that makes sense, but it would have surprised me greatly if I had seen code like that compile. And given how little benefit it really provides, I don't think that it's worth the extra complication to the language. So, I'd be against it, but feel free to open an enhancement request. Maybe a compiler dev will take a shine to the idea. - Jonathan M Davis
