Q: Are there any other candidate output formats? A: Yes, we could add length information for a more mathematical style output:

reversed(['h', 'g', 'f', ... to 8 objects]) The very presence of len might be a strong argument for providing the new repr, and its absence an indicator to avoid such.

This is essentially getting back to what Armin was saying.. if iterators act more like lists, they will be easier to user and will open up some new doors for optimization potential. Adding a way to get the length of some iterators essentially makes them list-like or tuple-like.
