Just to be clear, generators emerged with Python 2.2. You can get straight up continuations, coroutines, microthreads and a truly fabulous menagerie in Stackless Python [1], though Christian Tismer, the Stackless guru, has decided to cull the herd a bit since Guido accepted Generators, on which you can build at least microthreads and coroutines. And ya better believe it: Generators+XML rock the park, for real [2]. Besides Python's powerful dictionaries, they are probably the most useful core idiom I've seen in a mainstream language through the glass of XML processing.
