Thesis, antithesis, synthesis. The example of looking for a row of 0s that skips the current row on the first non 0 can (now) be dealt with using constructs like named break/continue statements (in things like Java or C#). (I would not be opposed to making the inner and outer loops separate functions with returns, either, though) What the author said was true at the time, but has since been dealt with by having richer control constructs for goto-less ("jump anywhere") programming.
