I'm wondering if we actually read the same book. While there are many points where I decided not to follow PBP advices (e.g. Contextual::Return seems too clever dark magic IMHO), I always found that TheDamian clearly explained the why under the suggestion. Otherwise, I think that his 256 suggestions would have fit into some 20 pages, more or less.
That's why I originally avoided the book, my opinion based only on the title. I later picked it up based on monk recommendations, and it turned out to be much better than I expected.
It wasn't do this, do that; It was "most do this, here's why. This is contentious, and some people do that, it's important to make a choice and be consistent." I don't follow everything in PBP, but I learned a fair amount from it and it make me examine my own practices.
But isn't that a lot of the actual value of this book?
That it does indeed present the arguments why something should be done in a particular way?
And that these arguments allow you to check if they do apply to your own problems.
