Comprehensions have some other benefits too, for example, they're much less likely to be accidentally stateful. My general experience is that for complex logic, a comprehension is harder to write initially, but much less likely to have bugs when I get it right. That said, I usually won't use deeply nested comprehensions, but sometimes it actually is the clearest way to parse something (e.g. extracting a field from nested JSON.)
