1. I did allow for "rare exceptions". Some things do need to be explained outside of the code. Maybe we're not so different after all :)
2. There are a number of techniques to write such code. Before I learned them, I had NO IDEA. One is to take what would have been comments and use them as variable or function names. This includes (and I had real resistance before I accepted this) breaking out a variable of function only in order to give it an informative name. "Level 4" doesn't just happen. You work at it for a long time and sharpen your skills in that area.
3. To me, much of the art of writing software is to find ways to divide a complex problem into simple pieces. If my code is real complex, I look for simpler way to write it. And I look hard.
