How about 2 lower level building blocks that would make these things easier 
to make and think about.


Possibly function to take the next n items of an iterator without advancing it.

Along with a function to advance an iterator n ahead without taking anything.


These would be simpler and easier to maintain, and have a wider range of uses.
