Taking your question literally, it changes the behavior of an itertools.tee 
object 'tee', so that iter(tee) returns tee.__copy__(), rather than tee itself.

It was created for rhetorical purposes and has no known practical application.

Depending on your point of view it is evidence either for (a) why the iterator 
protocol must be strictly adhered to, or (b) that iterators and iterables cannot 
be disjoint sets.
