Winning the IOCCC is like writing a dark and stormy night; the code is written obscurely, except for occasional spoilers, then it is judged in a violent round of whatever which helps to understand the code (for it is in the Judge's domiciles that our scene lies), rattling the brains of many, and fiercely agitating the professional standards of most programmers that struggle against the darkness.
