Go right back to David's example and let's suppose that instead of just
printing each integer I need to make a list of such numbers and pass them
off somewhere else.  With David's scheme you can use list comprehensions.
With the while-loop approach you have to revert to the mylist.append()
idiom.  Adding list comprehensions to Python wasn't a necessity, but some
feel that it is a nice mechanism for certain situations.  The same goes
with intervals.  Sometimes it isn't best to look at things in strict
isolation.
