The vast majority of iteration has no need for the last-returned value
again, so why add it to every iteration? You can provide it yourself (or
propose it!) with a small wrapper class.  One of the beautiful things
about Python's iteration model is that it does just one thing well. 
This means it can be applied in more situations to more kinds of data. 
Then if you need more, you build on top of it.
