Personally what I find is perverse is that .join is a method of
strings but does NOT call str() on the items to be joined.
Neither do most other string methods:

>>> s.count(42)

Why should join() be any different?
Oh please. Because it also RETURNS a string. Of course count won't
return a string, it returns a count. But str.join is for "I want to
join these items into a single string separated by this delimiter". If
the output is to a be a string obtained by combining other items, there
is nothing lost by converting them to strings.
