I don't understand how using methods makes multiple
string types easier to deal with.

Suppose I want to define my own string-like type. How
do I arrange things so that " ".join(x) does the right
thing when x contains instances of my new type? How
is this made easier by the fact that join is a method
of " " rather than a free function?
