When I was still in the industry, our Ada vendor
implemented Text_IO.End_of_File thusly:

    ...
    exception
       when End_Error => return True;
end End_Of_File;

REALLY irritating when you set the debugger to break on
exception in a program that reads lots of text files
and like a good boy checks for EOF before reading.
