There is actual evidence to back up his original statement, and even to say that nesting increases defects. It's called cyclomatic complexity, and can be tested for quite easily. http://en.wikipedia.org/wiki/Cyclomatic_complexity http://en.wikipedia.org/wiki/Cyclomatic_complexity I wrote an article on a similar concept here: http://www.jasonlotito.com/programming/blocks/ http://www.jasonlotito.com/programming/blocks/ It covers one method I use to reduce the complexity of my functions.
