Ok just to come at this from another angle: my own (embedded C) code, after it had been gone over by a much more experienced and skilled maintenance programmer to bring it up to company standards. It wasn’t beautiful, even then, but it was crisp, super readable, and ironically closer to how I remembered it than the original. He hesitated to show it to me! Programmer ego and tact are funny things. Humbling, sure, but on the whole I was delighted.

The best - it compiled to the sane hex file.
