I'm ambivalent about changing so many functions to return iterators. It's cleaner for experienced coders, but harder to understand for beginners.

  Most of those changes get masked behind loops that I don't think either is very different for understanding. I think the plusses outweigh the edge cases.

    Having taught a couple beginners, I can tell you that what you see when you print a variable is very important. So, I guess it depends how these objects convert to strs, but I was assuming it would show a zip or map object rather than the result.

    what are the edge cases? what are the advantages of iterators? less memoryuse?

      Iterators get some of the benefits of lazy evaluation.
