I agree.

You could as well use auto and a block without statement before it to 
set the scope. But that'd look kind of ugly. A block without statement 
looks like you forgot an if.

Here's another simple fix for with();

int x, y;
with (whatever)
{
       .y += x; //.y references this is whatever.y
       ++x;     //x references local scope
}
