That entire conversation on comments is just wildly insane. Uncle Bob outright admits that he couldn't understand the code he had written when he looked back on it for the discussion, which should be an automatic failure. But he tries to justify the failure as merely the algorithm just being sooooo complex there's no way it can be done simply. (Which, compared to the numerics routines I've been staring out, no, this is among the easiest kind of algorithm to understand)

The whole thing is really uncomfortable; it's as if, after attempting the sudoku solver, Ron Jeffries sat down for a discussion with Peter Norvig, who was not especially diplomatic about the outcome of the experiment. The section before that, where they're talking about the "decomposition" of Knuth's simple primality tester, is brutal. "Looping over odd numbers is one concern; determining primality is another".
