Exactly my experience. I’m a big fan of self documenting code (intention revealing selectors, useful variable names, etc). But I also recognize (and include) the value of low noise comments that guide through the higher abstractions of the code; a sort of yen-yang complementary approach. So I was with the author through the first paragraph and then saw something that looked like Aspect Oriented Programming from the late 90’s complete with the weave and intermediate compilers.
