Ah. That's the Pythonesque way I was looking for. I knew
it would be a generator/iterator but haven't got the Python

oriented terms where I would override __next__() to
return a chunk of the appropriate size.
Give a man some code and you solve his immediate problem.
Show him a pattern and you've empowered him to solve
his own problems. Thanks!
Python's iterator-fed for-loops are its primary motor for calculation.
Anytime one thinks of processing successive items with a while-loop, one
could consider factoring out the production of the successive items with
an iterator. While loops are really only needed for repeated processing
of a single object.
