I would like to define my own function to be used by the 'Image attribute:

type Complex is record Real, Imaginary : Float; end record;
function Polar (X : Complex) return String;
for Complex'Image use Polar;

I can't see what implementation problems arise... but I'm no expert.
Maybe it doesn't add enough usefulness to be worth adding though.
It would simplify some of the code I write somewhat, by eliminating
"Image" generic function parameters, added solely for easy debugging.
