The laziness, meant as deferred procedure calls *CAN* be used in Python, also in iterator context, through generators, that's true. But still there are no update'able automatically thunks, no lazy data! If generators remind me of something, it is co-routines.
Yes, they are becoming co-routines, you can now send data back into them.
If I can put a lazy list comprehension in place of a strict one, why is that not lazy data?
Look, I am not arguing that this pseudo-laziness is a central feature of Python, or that Python is close to being a functional language. I don't think Henning meant to say that, either. But there are some features like that, and they are very nicely done, people like them. Even before I knew about Haskell, those were the features of Python that made me really enjoy the language. So I agree with others who wrote that pointing out beautiful Haskell-inspired or Haskell-like features in a person's current favorite language might be a good way to encourage that person to have a look at Haskell.
That was my point, yes.
