Citation needed? What informal movement has there been, and where? The only problem with itertools and comprehensions is that you get code written in two different ways. I don't recall seeing anyone say "don't use a comprehension if you're going to then use itertools.tee on it" or anything like that. Maybe I just don't hang out in the right places?
