Are you saying that STDIN is getting opened and closed every time a line is read? I guess that would explain why there is nothing there. :) How about a small variation where I need to print something (a prompt or line number) on the terminal before reading the line (so I couldn't have <> in the loop control)? The (broken) code would be something like: 
while ()
    {
    print $foo;
    <>;
    last unless /\S/;
    print FILE;
    }
