Occasionally I'm using if (auto ary = func()), despite the fact that

I wonder if it's possible to fix this, as it is, IMO, the only
legitimate drawback of this change. Could we make the following work?
if((auto ary = func()).length)

I would have though this would work:
if(auto x = foo(), !x.empty)
That's because it means this:
if(auto x = (foo(), !x.empty))
which I think would be invalid since you are using x before assignment.
