Like the best programming tricks, this one is the right tool for the job in certain situations. The sleaziness of uninitialized data access is offset by performance improvements: some important operations change from linear to constant time. Alfred Aho, John Hopcroft, and Jeffrey Ullman's 1974 book The Design and Analysis of Computer Algorithms hints at the trick in an exercise (Chapter 2, exercise 2.12):
