It's getting less so over time, starting with bytecodehacks <wink>.

When they're the right solution, nothing else satisfies.  If you haven't
looked lately, the spam filter you're using contains about 100 yield
statements (the tokenizer is one massive distributed generator, although
more-essential use of generators was made in the statistical testing
framework, to chew over tens of thousands of msgs in a memory-efficient
way).  I've found bread-and-butter uses like that so natural that I had to
think about whether I've ever used generators at all(!).
