Fair point on the QA, I might have some strong take there but it’s a chapter I’d rather not open now, but I guess the point of my post is on the last sentence of yours: is looking at the code really necessary to prevent headaches?

I have started delegating chunks of code without looking, and many times when I do look for one reason or another (I still want to know the big picture!) they looked good to me. So my idea it’s just that it could work, but I’m still experimenting as most of us :)
