Because when you are writing debugging statements, it is
a time when convenience of writing dominates maintenance
and readability concerns (since they don't arise). So 
that's when 'Img is useful (although we had in mind 
originally that 'Img should remove the dratted space
in front of integers and also allow arrays, records etc).
(again for convenience of debugging).
