True. (But that doesn't mean I think using generators for this example
is great either.)

Remember that this particuar example was invented to show the
superiority of Lisp; it has no practical value when taken literally.
If you substitute a method call for the "acc += incr" operation, the
Python translation using nested functions is very natural. For larger
examples, I'd recommend defining a class as always.
