Trouble is, it makes some sense either way. I often put the larger
argument first - for instance, I would write 123412341324*5 rather
than the other way around - and in this instance, it hardly seems as
clear-cut as you imply. But the function can't be written to take them
in either order, because strings are iterable too. (And functions that
take args either way around aren't better than those that make a
decision.)
