Which, more or less works, for a literal translation of the straw-man above. However, you're missing the point. These deferred operations actually return results. Generators offer no sane way to pass results back in.
that's why you need a context object (=self, in this case).
def iterman(self): yield "hello" print self.data yield "nice weather we're having" print self.data yield "goodbye"
If they did, then this use case could be mostly served by generators.
