There is an important reason that many people forget. Compare:
    put_line (Integer'image(I));
with
    put (I);  -- Assuming proper instantiation of Integer_IO

If the line length is bounded and there remains not enough space on the 
line to accomodate the number, the former will write the number "across" 
the line break, while the latter will insert a EOL mark before the 
number and write the whole number on the next line.
