Yeah. It would definitely be useful to be able to do like you do with a for 
loop with an if, but in that case, I'd probably suggest just making it look 
like it looks like with for.

if(auto x = y(); x != 42)
{}

That would be really cool, but I expect that it would be hard to talk Walter 
into it.
