But now you're talking about an upcoming feature in DMD, right?

AFAIK, in current DMD, I can't get any help in avoiding patterns 
such as

     char[] saved_line;
     foreach (line; File("foo.txt").byLine)
     {
         saved_line = line; // should give error
     }

Right?

Are you saying that adding DMD support for qualifying `line` as 
`scope` is not the right way to solve this problem?
