Ok, I'll try once more: What does __setitem__ have to do with
**iterability**, not mutability or indexability ? I was commenting on
Maric's post that although some objects are typically iterable, they
are often treated as atomic by some/many/most applications  (e.g.
strings). It's not rocket science.
