- As he said, backtracking. The alternative would be to include yet another
- function call in each successive if-sentence, making the code ugly.
- Using gotos, the code _can_ be made to express the intended flow much
- better, as in his example.

- Are there any other languages than Prolog that implement a "machine" for
- backtracking?
