Sometime ago I asked this question at SO [1], and among the responses received was paragraph:
- `zip` re-uses the returned `tuple` if it has a reference count of 1 when the `__next__` call is made. - `map` build a new `tuple` that is passed to the mapped function every time a `__next__` call is made. Why can not `map` use the same approach as `zip`? Also it turns out that a faster solution looks not reasonable, since it requires additional calculations..
