The finer details of the coding advice in Clean Code is also insane. There’s a good summary of it but I forgor where.

See

By the way, "Uncle Bob"s prime number generator example discussed there (which Bob Martin, as he admits himself, does not understands any more in spite of that he himself published it in “Clean Code”) was originally designed and published by nobody less than Edsger Dijkstra and was used as an Example of Literate Programming by Don Knuth.

They are giants on whose shoulders we are standing. It is totally worth it reading first Dijkstra’s Chapter, then Don Knuth’s text, and then John Ousterhout’s discussion of Martin’s rewrite (linked above).

Or perhaps starting with Martins code and see if you understand it…
