My code uses 'Image heavily, because it is usually the neatest and the
clearest way to format many strings that mingle words and numbers.

I sometimes have to pass the result of 'Image to a function that
implements the kind of functionality people are asking for,
and it would be even neater and clearer if I could get that with
parameters to 'Image itself.

None of that output has anything to do with debugging.
