Well, that seems more informative to me.  Now you know that you're
zipping together two list iterators.  By "readable" do you mean
shorter?  In my opinion the size of a repr is less of a concern
(though not insignificant) than the usefulness of the information the
repr contains.  The fact that some objects (like list iterators) don't
themselves have informative reprs is an issue for any object with a
custom repr that reports it's attrs/args.
